I've had a similar experience. Tried lots of skis this year (5 different rides), and decided the R2 had the best overall feel for me. Coming off the 2017 nrg, I will say that I was not as immediately comfortable on it as I was with the original model. (could be that I spent weeks and weeks trying new skis and playing to my inner-tweaker, right?)
Anyway, I've always thought that at some point late in the season I'm just happy to be behind the boat running passes, and am no longer expecting to go very far up the line. But the R2 has continued to get better for me as the water gets colder. Still running passes in 50° water and a wetsuit that I'm not guaranteed on the best of days mid-summer. Really looking forward to starting the 2022 season on this thing!
