Honestly, im not trying to knock this tree arm or anything, but if you are going to spend the $600, you might as well spend a little more and go with our arm. I saw this arm at the shows this year and it is basically a CHEAP built version of our arm.
IMO this arm is overpriced for its cheap build. If this makes a difference, i would buy the muddy arm before i would buy this arm, regardless off the price difference
