I did the same thing. The fork is insanely good. I've tried Rockshox 32TK Air on a Cannondale not sure on model hard tail, and found the Raidon to be better imho. I tuned both to similar sag, and tuned the rebound as I went on the Rockshox.I did the Suntour customer loyalty program upgrade from the (For Light duty trail riding only) SR fork to the Raidon on my old 29er HT.
Having never been on a better fork the Raidon transformed my bike and my riding.
On my full squish now with a Rockshox XC 30 TK and its fine but I think the Raidon would be a step or two up from the XC 30..
Goes Like this If I understand what I found on the Raidon,
coil on one side, Air on the other leg and 34 mm tubes.
Lockout and rebound damping only.
Some good Info here:
SR Suntour North America | SR Suntour Customer Loyalty Upgrade Program
That Raidon is a $350 fork, Through the upgrade program it cost me $189, my local bike shop charged me $30 to cut and mount it. So, If I needed a new fork tomorrow the Raidon would be the first I would look to for my 27.5 full squish.
