Commenting with '21 Khaos 155" ser. 8 experience and to sub because I 'checked a '22 Matryx Slash Khaos 165" ser. 8, amd still trying to figure out what settings are best, and whther I should switch my 22 snowcheck to a Pro.
I find the 155" Khaos to be too much of a one-trick pony toy and not enough of a tool unless most to all of the Khaos lift is tuned out by softening the FTS and stiffening the RTS. In very deep powder, you MUST have the RTS fully stiff and the front mostly soft, or it's just one stuck trench after another, even when already carrying momentum, at least in 155". I would get out of the trench, pin it, should have been out, stuck again 3' later. EXTREMELY FRUSTRATING when you know yous other sleds would be at the top of the mountain by then. I and the people riding with me were cursing the sled, and it made me miss my 165 Summit 850. It's fine on hero snow and not climbing steeps straight, but once you want it to point and shoot up a line straight, it's simply never going to be close to a Pro, at least in 155.
I do enjoy messing around, especially when it's not deep powder, trying to learn fun maneuvers, the ability to lift the skis "enduro wheelie style" on demand to clear obstacles, reset my line, and enjoy a fun but probably false sense of "action" in my riding, but I don't like that even with the rear suspension "locked out", I HAVE TO mess around and swerve around, losing momentum, to get up steep and deep, and that during steep side hills, when blasts of throttle are applied, instead of pushing forward/across the slope, it tends to whip uphill as other have said. The ease of initiation is great though.
I am hoping going up to 165 in the Khaos wil help it not trench as badly and climb better. I do expect the have to dial some lift back out of it still, but hopefully just not as much as with the 155.
Really hoping that with the right suspension tuning the 165 Khaos will be possible to make it float, move forward, climb a little more like a Pro than the 155 Khaos (Burandt said it does in a video) but still have some of the "poor man's turbo" instant ski lift and effortless edge initiation and agility on climbing lines.
Are 165" Khaos riders managing to climb steeps without *needing to* inefficiently swerve all over the place, losing momentum, and dial lots of lift out of their track suspension?
