Best barrel for marb's

[Deus Ex Machina]

hey got a question that im sure has been asked a million times, but here goes, got a freind running a spyder tl+ with nitro, using marbilizer paint, what barrel is a good match for that paint and setup?
im aware that the autospirt is .686 and an almost perfect fit for it, but they dont make on for the spyder? im lookin for player oppionons and to see what a wide variety have found to work with a simaler setup

I like Marbs. I use them in my Micromag with a BOA Snake Bite barrel.

Anyone try the new Opera 7.0? It seems to work pretty good so far.
