I' ve been shooting PSE Carbons Dominator 300' s... Before that Beman ICS 400' s. The Nova bow has been used and abused in the boat chasing after Carp shooting heavy fiberglass arrows... So it doesnt surprise me, But my PSE F-1 has been abused more then the nova and that bow has yet to have any problems. I brought my bow to a semi-local sporting shop today and the owner said he' s seen this problem on three bows already this year. I think it maybe a common PSE problem.
