Outer Limits 4x4 Board

Getting a mate to bend up a stainless snorkle for me but was wondering if there is a "Best" size for it?
Was thinking a 3" one but then is that too much air?
I have no idea on what would be best and although my mate said he would make a couple if he had too would rather not piss him round
Cheers

have a look in the members thread under viper's mav shorty.. shows u my custom set up.. used 85 mm steel tube and prefab elbows welded on rather than having deformed bends. looks awsum.. not mine is facing back for lpg purposes but u could face it forward very easily
