i am not on brunswicks staff nor do i receive any free equipment from anyone. yet i choose to buy and throw brunswick exclusively. rest assured everyone on this site will get an honest evaluation from me. i will get my first chance to try my c-system 2.5 on monday. the owner of the house i bowl my mixed league at will put out a fresh shot for me to evaluate this ball. my 2.5 was drilled with the pin right next to my ring finger, the cg is stacked, and the psa is slightly to the right, and below the thumbhole. there is a 1" hole about an inch below my axis. the surface is 2,000 abralon and polished.
