Crash90, I'm using the Pefa LL cannisters (same setup that Kris used, and I'm now starting to get the same numbers Kris got with props). They are HUGE, but fit nicely in my Wild Hare 330, and the combined 110/cannister weight is still 3 ounces LESS than a DA100 with stock mufflers.

I use Amsoil 100-1 oil mixed at 80-1, and I've got 14 gallons of fuel through the engine.
