Yes, I competed last year as a 77. It was lots of fun, even though I didn't lift as well as I hoped. I hope to attend next year as well.
I think Jim Storch is the Central region's coach and he's a great guy. Keith is great to talk to as well.
69s have not seen full rosters the past 2 years if I remember correctly, so qualifying and ultimately medaling may just depend on who shows up. Regardless of medaling or not, the games are a really great experience. Good luck!
