J&J definitely if you chop a ball, after a few shots you're shooting straight again.
anything over 16 is overkill, but 16 it much too long to play any small-ish bunker. I bought a 16 inch barrel because I couldn't find any 14 inch ones in stock..I'm still kicking myself for not waiting for 12 or 14 inch ones to come back in stock.
Yup, another vote for J&J. I'm one of those that prefers the 12's and 14's. But like Kaz said, the 16 isn't overkill. Anything over 16 is...but 16 is still a useable length, I prefer shorter though.
