For what it's worth I am brand new to the sport and my first sled is a 2022 Khaos Matryx Slash 165. I have rode other sleds, but nothing super serious since they weren't mine. I was in McCall last week and rode my buddies Khaos converted 155 slash doing the same stuff right after I got my sled (got it while I was down there). The 155 felt tamer climbing, not sure how he has his setup, but it wasn't uncontrollable or anything, honestly felt like the 165 with his setup, the big difference being the 165 climbed better. From the very start it hooked up better and pulled to the top faster, which is to be expected. But I really felt no difference other than the 155 seemingly being a little easier to handle just because it wasn't pulling as hard. Mine does have full Ibexx clutching minus the cover. I was worried about going with a 165, I figured it was going to be kind of a boat. I am kind of weight sensitive, I'm tall at just under 6'5", but I'm only 180lbs without gear so things tend to toss me around a bit, but this sled was amazing. I am actually extremely happy with my purchase. I think having the extra track is helping me get traction and learn easier and it really feels no different from my buddies 155 other than it takes a little more to get that front end way up on mine. I don't think I could have picked a better sled to learn on. Not super planted so its a bit playful, but not overly playful to where I am out of control and it has been powering me through alot, though I am also not afraid to grab every bit of throttle it has haha. I don't think you will regret it, but I have little comparison to 155 so take what I say with a grain of salt lol.
