I’m a Nils guy myself but it’s a shaving head and if you’re around dirty ice, it might not be the ticket. I went with Nils due to the lighter weight, proven commercial engine, longer standard drill and drilling speed. Plus, if my engine ever craps out, I can use the drill manually in a pinch without much comparitive effort. Strikemaster comes close with their Honda/Lazer pairing from what I hear.
I have used friends’ Jiffys (Model 30 and to a lesser extent Stealth) and even though I’m a fairly big and relatively strong guy, throwing those things around the ice all day is considerably more tiring than my Nils.
