I voted other because you don't have the FG MT on your list.

I only have an FG Leopard Race, not an MT, but bigger than most stuff on your list, and then it runs on ordinary unleaded petrol, mixed with 2-4% 2 stroke oil. It also runs fine at -15C, which is an advantage, when you live with temps. like that for 4-5 months a year.

Bigger IS Better

Next time I will go for the FG MT or a similar one
