Wow. Ok, I took my Yonex RDS 003 to a stringer at Chicks Sporting Goods, and blah blah blah. So when I got my racquet back, I thought it looked a bit weird. Turns out the stringer took off something and restrung it, and I don't even know if its important or not! THIS THING That fat little part sticking out isn't there anymore! Underneath there's still this black guard-like grommet piece that's preventing the strings from rubbing against the frame, but that thing is so thin!. I stuck my nail into the guard and it actually made a deep indent. Can anyone tell me if this is a big deal?
