I’ve got a Stumpjumper Evo, and think it works well with the stock Float X.
It’s not designed to be a super-plush winch and plummet DH plough, that’s what the Enduro is.
It’s at it’s best as a poppy and playful trail bike with a little extra margin for error and tons of adjustability.
I had a coil on my previous bike, a 2017 YT Jeffsy 29. I do like them, and they make the bike feel plusher. If I was going to fit one to my SJE, which at the moment I wouldn’t, I’d go for one with a hydraulic bottom out like the Rockshox.
Maybe it’s just the riding I do, but in the Alps on my Jeffsy, I quite often found myself feeling underbiked. On the SJE so far I never have.
