UPDATE:
The 8100 are perfect for me. I am not sure what more one can realistically want. The issue is that even at the softest compression they are more capable than the front on stiffer springs
The front can take a tiny bit of air with no issues but bottoms easily on specific types of rough spot (think narrow dip then a sharp rise).
The new 8112 with compression adjusters is delayed half a year. The 8112 without adjusters is not available at the moment.
