The competition (week 87) didn't run yesterday.  It was delayed until today.  Kicking off in just over an hour: https://www.youtube.com/watch?v=Ebo0tMfrLlM.

There hasn't been an update here for a while.  Channing has started a new thing with the OSC.  He's giving out a (digital) badge to the overall winner (combine scores of 13m and 20m) every week.  He's not sure what he's going to do with them yet, but the tallying has started.  The last slinger to win the badge will have it displayed in their round video the following week.

I won the badge the first week this started.  Big Ray got it the second week.  And our boy Channing won it the third week.  Today's comp will be the 4th week and we'll see who takes it!

Here's a couple pics.  This was my entry after winning, and Ray after the second week.

No modifications to the tennis balls.  The intent is that everyone is using the exact same projectile.  I recommend sticking with a good brand, such as Penn.  If you look around ebay you can usually find a good deal.  Cheaper brands are lower cost, but they just start falling apart.

How long of a break do you mean?  Ultimately it's up to you.  I think most guys just go right through without stopping (other than to tell the camera what round they're on).  I do break up my own rounds when I record them.  I (obviously) start my 13m round on the hour and throw the first 5.  I then wait until 2 minutes after the hour (usually about a minute wait) to start the second 5.  My 20m round is started at 10 minutes after the hour, and using the same two minute span, the second 5 balls at 12 minutes after the hour.  I like having a short separation like this because it adds an aspect of live competition.  At the World Cup in Ibiza, competitors with throw 5 balls, and then wait for everyone else to go before throwing the second 5.  It can be a very long time between sets.  I like including the separation even if it's only a minute break.

If you're thinking about short breaks like that, no problem at all.  If you're thinking of longer breaks, just reach out to Channing and let him know what your plan is.  If he has any concerns he can let you know.

Hope to see you in the OSC! 

I updated the first post with this information but want to make a post about it too.  As mentioned in other posts, this year the Slinging World Cup will change to FBTF (https://tirdefona.es/en/) distances for competition.  In short, the 13 meter distance will increase to 15 meters (49.2 ft).  Tennis balls will still be used.  That distance change won't be official for the OSC until the World Cup is over, but if you want to back up to 15 meters now to start practicing, it's all good.  I'm not sure who all is.  I know Channing and his crew are slinging at 15.  I've backed up and so has IronGoober.  Again, this isn't required right now.  13 meters is still totally fine.
