After a over 50 years abstinence I am returning to the sling fold.  I already have a couple slings in-hand, but have not slung any projectiles, still awaiting delivery of hard foam golf balls.  In watching several YouTube videos I see sling ends that taper down to a thin tip, and crack like a whip when launching projectiles.  They sound pretty cool, though losing any stealth in the process. 
Anyways, one of the slings I purchased is made from a single length of 550 paracord.  It looks great, but one feature I was trying to figure out was the row of 3 beads at one end.  According to the maker the bead end is the one you let go when launching a projectile.  What are the chances of a neophyte such as myself whacking myself in the head with the beads after launching?  Have any of you here seen this style of beaded sling before.  Would you recommend I remove the beads, and maybe add a tuft of fuzz to slow down the tip?   Thank you for the feedback.

I decided to remove the beads, tie off the end, and cut at 3" beyond the knot, and create a cracker cutting out the white paracord core threads, and using the outside sheathing threads cut at 3".  My golf balls don't get here until Sept. 4th.

    I have been known to attach one wooden bead before the release knot to keep my sling from cracking when I wanted to be stealthy.  But this isn't something I do often. Normally like the bullwhip crack. 
I can't imagine any practical use for three beads.  I would have removed them too.

I've done quite a bit of slinging with some pretty big stuff.  If a fist grip is being used, I think a single knot that is positioned outside the closed hand works very well.  I attached an image below to demonstrate.  I think the largest stone I use with this grip was around 7 lb.

And when slinging very heavy stones without a fist grip, I used a hold that I referred to as a finger-lock grip.  It's just a single knot that is clamped down with the index finger.  Again, images are attached to demonstrate.  I was able to sling a 5 lb stone with this hold and only a single strand paracord sling.  I do highly recommend a glove if doing this.  It's an incredibly strong grip though.

Beads could possibly be helpful in certain situations to add extra stuff to "hang on to", but I think additional knots in the cord would work better.  As you said though, it's all personal preference.  So whatever anyone wants to do for themselves is fine with me.  And if beads are added just to make the sling look pretty, that's fine too.

I just got my shipment of 40 foam golf balls to play with, hopefully my Balearic sling will arrive this week.
Thank you all for your input.
