Absolutely love the fact that Uukha actually marked the limb bolts with the minimum, medium, and maximum travel ranges.
I did have an issue with the magnetic clicker extension/plate thingie; can't get it to stay in without shimming it with a bit of dental floss, but to be fair I did take two extensions and glued them together to get a longer clicker reach, so it may just be that mine is too long/heavy for the magnet's designed use... My new outdoor arrows will be quite a bit shorter so in the future I'll try a shorter extension and see if it stays in place... Didn't notice any loss of "attraction" with my modified extension, still fits snuggly and seems to lock in place, just doesn't stay in during use, but again I'll have to try the unmodified extension to know for sure whether it's the bow or the modification.
As for weight, honestly couldn't say because I don't have an aluminum riser to compare it to, but it doesn't really feel like "light" carbon; it's pretty solid and no real cutouts. Without putting it on a scale, I don't know or think it's any lighter than my 27" CXT; the Uukha just feels "solid" to me and my limited experience.
The limb "pockets" concerned me at first; before getting this riser I listened to a YouTube that criticized an entry level riser for a limb mount that wasn't really a pocket, then I get what I think is a similar design on this higher level riser... but so far absolutely no issues that I've noticed.
R-Core is finally making the grip design I like for the Pro 2, but I did have to shim it a bit with tape as it rocked fore/aft slightly... To be fair it is reportedly a hard grip to reproduce
