I run a Madsen's hot rodded 395XP with a 42"-48" bar, and a 3120 for my bigger saw needs. I use a 550XP with and 18" bar for climbing duties, and a 562XP with a 28" bar for a mid-size chunking saw. All of em' kick ass. I have been, and will always be a Husky man! Also want to give a shout out to the TreeMotion S. Light. After climbing in the same old floating-dee saddle for 25 years, I went on a new saddle quest last year. Tried the Matt Cornell, regular TreeMotion, Onyx, Monkey Beaver, and Ergo, but the S. Light beat them all. I am amazed how comfy and light this thing is once dialed in. I had a 395Xp hanging off me for 3 hours recently and could of keep on going! Stunning saddle!!!
