What is the best performing barrel for a spyder paintball gun?

I currently have a Spyder MR1 paintball gun which came with its 12″ standard barrel. I definitely want a new longer barrel and was wondering which barrel you think is the best to buy. I’m looking for the best performance wise, meaning whichever shoots the most accurate, farthest, etc..

Any knowledge will help…what size, type, or even just which barrels stink that i should not get.
Or a site that has it would be great. Thanks for anything
Is the 16″ Aero Twist Barrel any good for anybody who’s used it?
