I've ordered a Nobby Nic Evo 29x2.35. Will let you know how it compares to the Maxxis Ardent it's replacing.
I'm embarrassed to say this but despite a valiant effort with metal DH tyre leavers I couldn't get the 2.35 Nobby Nic onto my Stan's Crest rim. This is the first time i've ever had to admit defeat with tyre fitting?!?! It's going to have to go in the classifieds if anyone's interested? (Brand new, boxed, triple compound EVO / Snakebite version)
I bought and fitted a 29x2.3 Specialized Purgatory instead; £10 cheaper than the Nobby Nic and only 40g heavier with much bigger nobbles on the tyre shoulders - something i've been after in a 29er tyre for awhile.
First ride out I couldn't fault it, a slight increase in rolling resistance over the Ardent, but a big increase in grip; the Purgatory just feels solid and dependable if you know what I mean, weight the front tyre, lean the bike and it just seems to hold your line. Conditions were bone dry but dusty and loose in places. I'm running it with a Maxxis Ikon 2.2 on the rear.
When the rain arrives i'll let you know how it goes in the wet, and i'm also off to Wales for a few days next week so will see how it manages rockier terrain.
