On a number of racquets I use the so called load spacers on the ends as the billiards are small, and those spacers spread out the forces.
I use them a lot on Princes O port racquets at the 12 oclock position as it holds the racquet better as that racquet is curved as well,and on other racquets that I think it would be best to use as it spreads the load over a greater space.Those are those little plastic pieces that came with my machine (Xtremesportsmachines Pro Master 6 point).I assume that most machines came with those little spacers, as they just fit over the billiards.
Don't know much about the Gamma mounting. It may be different.
Just curious, does anyone else use those load spacers?
