I’m using all 3 methods atm, Procore, Deaneasy and ghetto using a road tub. Out of the 3, official Procore is a doddle to fit, the other 2 more hassle.
I race DH and gravity enduro and it’s def a game changer as wouldn’t dream of running pressures below 20psi prior. I now run 17.5 Fr and 18 rear whatever the terrain and grip is phenominal!
It’s just me needing to get used to it is the problem as I haven’t pushed it beyond it’s limits at all.
For normal use, if you regularly pinch flat or burp tubeless then I’d recommend it, if you’re getting by ok on tubeless at those pressures, then £100+ is better spent on good tyres and stans race fluid.
