For me it gives a better feel at the release. Without inserts I can not really feel it come off my fingers. With inserts, I get a little burn and I know that I threw it correct.
I am sure there are other reasons, but for me this is why I use them.

BOWLING IS FUN NO MATTER WHAT YOU SCORE. BUT A 300 IS ALWAYS NICE.
STRIKE ZONE, ONSLAUGHT & PYRO. STAND 22 AND THROW 10 OUT TO 5 AND CRUSH THE POCKET. AT LEAST THAT IS THE PLAN OF THE NIGHT...
GOOD LUCK AND GOOD BOWLING!!!
