I’ve had the KS i950 on a stumpjumper throughout winter, as above didn’t realise how handy it was to be able to adjust on the fly.
Initially I fitted it without the remote, but added this recently which has improved dramatically (recommend going with it from the outset).
Had the reverb been available I’d have gone down that route, but certainly not disappointed with the KS.
Huge benefit when in doubt / misjudged whats ahead, or even being able to raise the seat for a short sprint / rest in between the clatters.
Only hassle though is can no longer fit an under saddle bag for tools etc, so everything has to go in a camelbak plus adds circa 500 grams to the mix.
If you can fit the longer version(s) deaf would, I’ve got the 400mm with approx 100mm above the seat collar which allows full extension and sufficient drop.
