I have the tuners on an 03 RX1 that I have upgraded to be basically a carbed 07RTX. Torsion rear suspension, Attack front end, Clicker GYT-R front shocks and Rider fwd seat and riser from and Apex. I have the tuner skis I bought from someone on hee and they work really well on my set - up. Very happy with them. I have 4" stock carbide on the inside, 2" on the ouside. Actually the carbides were on them when I bought them 3 yrs ago.
I have no darting, zero ski lift and the steering is about as light as can be expected on an RX1. I do pick up some push in certain conditions when riding aggressive but all I do is slow down a bit. I had stock saddlless skis on it, Tall Keel at 1st, way too much ski lift, darting was bad. Went to the mid Keel and was better but still fought ski lift like crazy and both were too sensitive to conditions. Especially hard frozen trails. They were ok when the snow softened but still never cured the ski lift. The tuners did and am very happy.
