Thanks very much jimPacNW. Those are helpful comparisons.
I do have the Rocket Rons on the list too.
This website did what I thought was a fairly helpful rundown of some of the sort of tires I am considering, and it characterized the Rons as basically a lighter Forekaster. I am not a racer, just an enthusiast. I want a light/light-ish tire, but don't need the absolute lightest. I also do not need a super tough sidewall. The XR4/XR3 TIs (non-SEs) are doing fine in terms of sidewalls after about 500 miles on my local trails. I like how supple they are at their sidewall/120 TPI/weight, so a relatively thin sidewall is OK with me. My bike came with DHRs, which I rode for awhile before swapping in the XRs, and I have not had any issues stepping down in terms of tire toughness.
I have looked at Vittoria tires too, so thanks for that rec. Even in 27.5, there are quite a few choices. But we all know no matter how many, there are never enough. I kinda wish Maxxis was making the 2.4 WT/XC Aspens or Rekon Races in 27.5 and not just 29. Although maybe a little more pure XC than I'm shopping for, the WT/XC is "optimized" for 30mm iw rims, and I'm basically right at that iw. Need to get Nino Schurter or Kate Courtney on a mullet I guess.
In any event, I am looking forward to trying something different. I figure trying 2.6" in a different brand/tread, after the DHRs and XRs all around 2.4", will give me new food for thought. Maybe after a season on those I'll try something on the narrower end. Fun to give various approaches a go.
Thanks again for the help
