i have a predator sneaky pete wood to wood joint but with a 314 uni-loc right now. my question is do i need to send my butt in to make sure the new 314-2 i buy will fit? or should i be able to order it without sending my butt in? i'm going to be ordering it from seybert's billiards but i wanna know if i should sent my butt in or any. any advice would be great guys.
