I have been running a spool in my 14b for two years and it has been OK. I just bought a Grizzly locker to put in because the spool pushed me off lines too much. Even though they say the Grizzlys are supposed to hold up when a shaft breaks, I'm still concerned about the stock 14b shafts. Has anyone tried having stock 14b shafts cryo'ed, and if so did it make them hold up better?
