I'm 135-140 lbs. I highly recommend the Ikon 2.2 EXO TR 3c. They're my favorite tire for 3 years now, made even better when they made a TR version. Every non-DH tire I have are merely beater tires that I am trying to wear down on pavement now. I have about 8 of them equipped on various bikes in my quiver. I feel no sting when I pay the $65 or so per tire. I believe tires are one of the best places to spend for pure performance, if not *the* best.
I've run narrower Vee Rubber 2.1 (were more like 1.9 visually) tires to avoid wearing down my nice tires on pavement, and found that they ride surprisingly well. I didn't want to experiment with tubeless, seeing its plain bead, but its tough casing warded off flats well enough running tubes. I didn't really suffer at slip until it started getting balder, but still ran it to squeeze more mileage, since it was fun getting sketched out and confronting the challenge of having less grip made things interesting. I credit the rubber compound, which seemed like a Maxxis MaxxPro 60A, but it wore out in 25% of the typical mileage I get out of an Ikon.
I've run wider Racing Ralphs. They squirm a lot, folding when I push them. I don't have much confidence in them. In the rear, they like to fall into ruts, needing a lot of encouragement to roll out of them, and likes to drift out on off camber turns. I suspect that the way the shoulder knobs are oriented and staggered makes it "walk" in an inward direction (left shoulder knobs want to go right when engaged). When I get going pretty fast and start to flow, they are buzzkills, tending to burp and feel like they're going flat. If I don't pump the bumps, or at least don't unweight the wheel, their bounce is a bit violent. It feels like an air spring with virtually no damping, the way its ballooned out nature bounces.
I've looked at the 2.35 version of the Ikons, and see they're scaled up. Seemed similar to how the Ardent 2.4 is so different than the 2.2 version, so much that it's almost a different tire. I actually bought one, but haven't found a bike I wanted to equip it on yet. That's the main reason I don't go bigger, since there's nothing with the tread pattern and profile and other features I want. The next step up is the plus sized range of tires, 2.7-3.0. Doesn't help that I only have 19-21mm ID rims right now that I like, with the exception of an I9 Enduro with Stan's Flow rims, which I've had on backup but probably should sell.
I've tried Nobby Nics, the new 2015 ones, on 941 Ibis rims, and bottomed it out on a tiny 1.5' drop to slight uphill (same drop makes a 2.35 tire squirm/twist on normal width rim, but not bottom out). I was not very convinced by the high volume trend in general, besides how the traction was more than adequate and how it didn't have low pressure squirm when pushed in the corners when combined with wide rims. I have my doubts if it's a decent substitute for just having a stout casing. Would need a longer term test to confirm. Riding a friend's heavier built Enduro 29, letting him ride my lighter built E29, I thought the DHF on Roval Fattie SLs cornered extremely easily. Felt like I could push it so much harder and tighter around bends than I usually do.
