I installed the kit on my 23 136 XCR, had all 4 shocks re-valved at the same time by Wentzlaff. I am going to be honest its hard to give an honest opinion on the linkage as I did shock valving at the same time, and I was only able to put like 600 miles? on this year... and most of those were in farm fields or on super low snow trails up north. One thing I can guarantee is the ride is significantly more plush, which makes sense as its supposed to make the pro cc more like an r motion. I would definitely do it all over again.
