I've shot probably half dozen 60 inch MOABs.....all were the same.
Smooth draw, no hand shock, quiet, and yes fast...as fast as some recurves I own. I've never had a problem taking game with any of mine as they seem to hit the mark better than me.
I have shot one 62"er, and it wasn't the same feel to me, the total package was in the 60 incher.
If there's any way you can shoot either before your due date, that would be great.
I"ve never shot the TStick III....but have no doubts is a well built shootable bow. And by its design and Jim's recomendation, it would be more forgiving. How much, I don't know, and that would depend on the shooter as well.
Nice choice for a bowyer either way.
