Need help choosing a barrel

[Celltic Shooter]

I bought an MR2last summer and am trying to decide what barrel i should buy. I'm leaning more tward the J & J but can't decide all of these barrels have pretty good reviews so need help from you guys THANKS:

J & J ceramic 14"

Smart Parts linnear 14"

J&J makes great barrels and between that and a Linear i'd take the J&J. CP and Proto are also two companies i'd look at when buying a barrel.

Im a big fan of the freak myself but ive heard pretty good things about J&J so i'd probably roll thataway between the two, if u go smart parts go freakishly
