C_A and Camo make some very good points, but I still feel that such an action would only hurt slinging efforts more than it would help.
Keep in mind that it's the arbitrary restrictions that made the Balearic ruleset so controversial outside of the Balearic isles in the first place. Otherwise we probably would've just adopted it instead of continually trying to reinvent the wheel. (For example, I prefer synthetic materials in my workhorse slings, and I prefer two rotations or less when I throw with them. Both are big no-no's in the Balearic ruleset.)
I'll compare my reluctance for a rigidly-micro-managed system to modern fencing, and it's drawbacks.
Sure, In the beginning it's fairly easy for newbies to get in the groove. However, it's that very same iron fist of regulations--many of which are just inappropriately silly for a martial art--that result in either constantly complaining/annoyed fencers, or fencers simply abandoning it all-together for more organic sword-based martial arts. (It was HEMA, in my case.)
Even if you ignore the logistical complications of supplying each and every slinger with identical gear, there's still the human aspect. You can standardize every little aspect, but people aren't identical. What works for one person will only serve to handicap another. A meter-long sling used in a figure-8 is going to behave differently for a 5' tall guy than it will for a 6' 5" guy. Sure, most may be able to get by... but if you give a novice an ill-matched sling and a make him use a style he doesn't really have an affinity towards, he'll do one of two things:
*Either he'll realize the restrictions the system is putting on him and be unable to do anything about it...
*He'll blame it on himself, ultimately convinced that he's "not gifted" and ending up quitting. (This is a very commonly-seen mindset, btw.)
Granted, if "set loose in the library", a beginner can quickly become confused and lost in tiny details from so many different conflicting sources. That just means we need an easy-grasped introduction to the sport for beginners. Something like a "Slinger's Guide" in book form... Gee, If only we had one of those: that would solve most of the problems novices' have! I wish a book like that existed! When you boil it down all you really need to know to get started is a sling about the length of their own arm, and some pointers on where to begin. (Slinger's Guide, YouTube videos, "where to begin" articles/forum threads, etc.) After that, they can experiment and dial in their preferences however they want. It's really not that complicated, and we already have tons of resources nowadays that keep readdressing this. No need to get hung up on it.
Anyways, do I think we should have an easily-accessible method for newbies? Yes! Do I think a tightly-controlled standard that everyone must conform to will solve this? Heck no. Do I think no rules whatsoever is necessary? Definitely not.
It's all about moderation: having everything regulated to the point that people are quickly starting to suffer from suffocating restrictions is just as bad as total anarchy.As for the "lack of access to a good sling" issue...
I'm pretty sure the biggest reason for most newbies not taking advantage of the Aussie pouch deal is because they simply don't know about it. Not because existing resources are non-existent, but because they aren't aware of all of the goodies potentially available to them! The Aussie pouch thread may be a sticky in one of the sub-forums, but I've known several people who didn't even know there was a forum on the website to begin with.
If we made sure to tell newbies about it, then they'd likely pounce on the offer. (I usually go a step further and carry a few pouches in my backpack and just hand them out when someone's interested)
What I think we should do to make it easier on beginners is have an easily-accessible and well-publicized "basic model" or two for beginners. Then you could simply keep a stock of them on-hand to loan out/give away at slinging clubs and events. Aussie pouches and seatbelt slings would fill this need beautifully. Then if they want to upgrade after a certain time, then they can do so at their own leisure. That way everyone wins: the existing slingers/slinging cultures won't be completely alienated, and the newbies will be able to join into the fray rather quickly.
[The part below is more casual preferences rather than stuff that I absolutely hate.]
However, I
am all for a standardized range, and to a degree, ammo. (Lead out-distances all other ammo, and can potentially poison the local environment.) For official events/tournaments, I'd recommend either carefully-chosen river rock, concrete, or clay as a decent-enough compromise between ease of access and manufacture while maintaining a "professional" appearance. (Mortar, concrete, and clay are fairly easily-attainable in areas without decent rocks)
It might be a good idea to make it only concrete/mortar/clay/stone initially, and then introduce a metal ammo division/event if demand is big enough. (In a way, like what baseball has going on with wood vs. metal bats)
Honestly, I have no problem if someone likes using some ball from another sport as their preferred practice ammo, but using rubber balls as the standard ammo for an international slinging competition would be like sticking suction cups on the ends of arrows in a high-level competition, or using a Red Rider bb gun for an olympic biathalon. Fair enough if it's only beginners in a short-distance event, but otherwise it looks silly if everyone is using them.
As for the "safety of modified rubber balls" aspect: if a rubber ball is dense enough to sling accurately over 25-40 meters, it's not going to be much safer than just getting hit with a rock/concrete glande in the first place.
I like the idea of just using the Balearic target with some kind of smaller sub target added to the center of the diana. The combo would work really well.
I originally voted 15, 25, 35, but after some more thought, I like the 10, 20, 30 meter classes better for simplicity's sake. And it should definitely be meters, not yards. I may be American, but I still think it's retarded and inconsiderate to continue being too stubborn, lazy, and short-sighted to adopt the metric system like the rest of the world. A short-term headache in exchange for a measurement system that will permanently ensure that cross-measurement confusion is a thing of the past? Heck yeah!
================================
TL; DR Version:
No restrictions for slings or their materials. (Maybe a long and short sling division at most.)
No restrictions on slinging technique.
Yes to the 10,20,30 meter distances.
Yes to the Balearic target with an additional inner "diana" of sorts.
Stone/concrete/clay ammo preferred. (Maybe metal later on, if demand calls for it)
