Wel for the flame control. You can get a simmerplate for a low flame mode.

Mine problem with MSR stoves, are the pumps. I'm not formiliar with the latest models, but the plastic pumps i have used where kind of flimsy and the little lugs tend to brake of with use.

If you going to use cannisters again, consider those little adapters to convert cheap valveless (or whatever they are called) to cannisters with valve. The valveless tanks are only one quid at the hardware store.
