I still have the rear Hyperpro spring on the rear. To cope with the spring weight I have been running full hard rebound. I backed off 1.5 turns 2 weeks ago and noticed an effect on compression damping. Felt a little plusher. I know it is a rebound setting but there may be some interplay with compression. Seemed to be a happy spot because no further affect with adjustments beyond that. The spring change seems to match the Bitubo front pretty well.
