I’m still fannying about with mine. The ones that might be keepers… Minion DHF 2.5 and DHR 2.3 is the best overall I’ve found but it sloooow, and heavy, you need to be using the grip to justify that. Slaughter adds speed and occasional terror. HR2 2.3 good for lighter use on the front. Shorty for the slop.
Got an Ardent on the way to try on the back, really want to find a 2.2 Captain. Hans Dampf I just thought had essentially no redeeming features, pretty horrible. Mountain King 2 just outclassed by the highroller 2. Xking wasn’t tough enough on the back, actually worked quite well otherwise but punctured for fun (I had one for the XC bike, gave it a go). Bonty XR4 just doesn’t quite get the compromise right I thought, it’s neither fast or especially grippy- got this on my rigid now. Vigilante was good but took second fiddle to the Shorty. Butcher, I love in 26 but haven’t gelled with in 29, need to try again.
