The Hygear linkage and dual pressure definitely makes a difference; I had it on a 141" Cat that we owned "briefly" before trading it in for a Sidewinder. I went with QS3 coil-overs on my 2016 XTX, and love them. I improved my ride greatly, and still have a fully uncoupled skid. At some point Yamaha gave up on the Floats, and started putting the QS3's on the 141" skid, and has carried that through to the new 146" XTX's, so they obviously recognized the benefit.
