I have a 15lb gravity shift that I am considering trades on. Not really looking for anything in particular let me know what you have to trade. Will not trade for anything old. Ball has approximately a 4 1/2 has slug and grips. Grips not included. Ball is in great shape. Has a couple knicks but nothing major at all. Can take pics and email to you. Great ball has monsterous back end. Just dont get to throw it alot around here. Drilled pin directly above bridge and mass bias in thumb very strong
