I've had both and i'm a lot like asmund, I tend to switch camps often. My current flavour is 2-stroke and i blame the OS AX series of motors for swinging my preference that way.

There seems to be a general shift away from the high revving 2-stroke towards the higher torque engines and these are the engines that appeal to me now. Partly due to economics of engine price and fuel costs, and partly due to the simplicity of operation.

My AX engines are serving me extremely well (i have .55, .75 and 1.20AX's) and i'm also keen to get my hands on one of the european .91s like the Webra .91-P5 or MVVS. Those engines are brutes and deliver power in a different way to what we've come to expect from 2-strokes.

I briefly costed the feasability of going all electric but the cost for an electric setup to match a 1.20AX is 400% more than glow power. I'd have to burn a lot of fuel to make it feasable on an economics basis.
