Jesus Vega,
Great to hear from you my friend! Welcome to the slinging.org message forum! I've been very excited to hear how you are doing. I've put up some of your writings in the topic, Federacio Balear de Tir de Fona. A lot of things that you wrote to answer my questions that were very helpful to me a few years ago.
I'm very very sad to hear about your shoulder

I have a war story too. I recently permanently hurt my wrist making bullwhips. My webpage is
www.whipartist.com. I was able to rehab it with ice but not good enough for whip making. I've been making slings though. Look in the picture gallery or at my website and you'll see some pictures of slings I made.
We have atleast one member who speaks Spanish. Archeorob: Rob. He could translate your sling throwing handbook. I think he may want a copy. I know if we could get a copy translated we would all enjoy it. He may be a good man for you to contact.
I didn't see your webpage link in your profile? You can post it on here if you want. I would like to see it.
Write on the board whenever you have time. We all are very devoted to the sling and we appreciate having a veteran like you as a member.
I am having a lot of sadness, hearing about your shoulder! Are you certain it's a permanent injury?
www.ctcream.com helps sports injury inflammation a lot. And so do ice bags 4 times a day for 10 minutes at a time until healed. I had trouble accepting my wrist injury, but it's hard to hear that you can't sling. I know you were very good! I've had a few long term sports injuries finally heal with ice, ctcream, and weight training. If not, maybe with enough practice you could get your other arm good? A good challenge anyway.
I hope you enjoy our website a lot Jesus Vega. Join in the discussion whenever you have time.
Long Live The Sling,
Ben
