I am relatively new to splitting and have been using a hardware store bought 8 pound maul. It's tiring work and have been looking for something to make the job a little easier. I've been reading a lot hear about the Fiskars Super Splitter and thought I'd try one, just not sure whether the 28 inch X25 or 36 inch X27 would make more sense. I am 5' 10" and weigh about 170. I'd be using it on a variety of northeast hardwoods of varying sizes. Any opinions? Thanks!
