Make sure to punch a few holes with them and see if you like a chipper blade compared to a lazer blade. I ran some Jiffys last year, personally I still like my 224 8″.
Jiffy was an awesome auger, cut nice, easy starts and I felt they have a leg up as the blades and auger freezing up compared to the other brands.
The things I didn’t like was they were messy, when you punched through they seemed to throw a lot more water and soaked your legs more than normal. As I got used to the auger I would throttle down before punching through and it helped, but still left me thinking it wasn’t the right fit for me and having my bibs more water logged than I have ever been helped confirm that. I punch a lot of holes in a day, to me the Jiffy felt heavier and bulkier than my Strikemaster and when you carry an auger around in 12″ of snow that makes a big difference.
Sad part is, in my perfect world I wish they made the jiffy power head with a Strikemaster auger and cutting system.
