Hey i would also like some info on macro line, i plan on using CO2 with it so if anyone else has done this please let me know how it worked. (good or bad)
Ive got macro line on my cocker, and its been used with both C0² and Air and its works fine!
I was advised to use it coz it can take a larger pressure than micro line!
Just make sure that when you cut the hose at the desired length, the cut is as close to perpendicular as possible, and that the cut is as clean as possible (no frayed parts). It might leak if you cut it badly. Use a new, sharp snapblade knife.
