i know some model of Strike master was a flop, something about too aggresive of a cut for the motor used. Just what i heard, not hands on.
I liked the Jiffy Stealth STX, didnt like premium gas ill tell you that much. Took a while to fire it up if it was cold, and it stalled out like crazy for the first 8 or so trips, when it was cutting ice. Somehow it smoothed out and ripped holes like crazy. Nice thing about jiffy is you can overlap holes and drive your quad into the bottom of the lake
Why not go green and use a IceGator? Blow your Jiffy out of the water. Something like 55 holes in 30 inches of ice on a single charge. Downside is biggest hole being 8 inches .... not 10"
