In my experience the Cromoto is very comfy in the shorter lengths, but the 465mm+ 29er versions seem to be a bit beefier around the top of the legs and not quite as comfy despite the extra twangable length, however they are still better than the MTB disc versions of P2’s that I’ve had over the years.
The old Pace RC31s were very comfy, almost to the point of being too flexy in my experience, and I bent a set at the crown/leg insert so they no longer on my favourites list.
Having said all that the differences are small so its nothing that 3-5psi out of a tyre wouldn’t cure/mask.
Any scope for bigger tyre? Or using a more supple lighter casing front tyre? It can make a big difference, especially if you’re using a bigger beefier carcass tyre.
Are you finding the problem is from impacts, or general trail buzz and micro-hits? The former is hard to deal with at a fork level, even the best will only just take the edge off things, and the latter is definitely better handled with tyre choice IMO.
