Well im going to try 6MG in 1.5 Ohm as at the moment ive only tried in 3.0 Ohm and 2.4.. If that's still the case ideally I'd want 8/10MG ... The Boge has burnt out in about 2 hours, Get what you pay for I suppose!
You do occasionally get a bad one in the batch, but I would expect at least a week or two out of one.
