High performance rear shock suggestion?

[the Ferret]

Take it from someone who also lives out in the woods with a fairly long winding curvy downhill driveway..one of the best things I ever did was to have the drive blacktopped ( the black absorbs heat and helps melt the snow) and to buy a big azz self propelled snowblower ...although for your drive I think it would be a big 4 wd ATV with a snow blade. Might as well have a little fun while you are clearing the white death off the drive.
