I switched from a Pure Aero with HyperG to using a Clash due to arm problems as well. I picked up some Kirschbaum xplosive speed during their sale, it is a pretty soft poly with decent spin. I tried Confidential but found that I was just not getting much power out of it, I probably should have strung it a bit lower. I'm currently trying out HyperG in the main with Synth Gut in the crosses, it's working well but doesn't feel as good as the xplosive speed. This hybrid might work well for you since you want the HyperG feel but a little softer. There's also HyperG soft, I just bought a set and will be trying it out soon.
