Both of those selections are way overkill for your application like others have mentioned. You won't see any true benefit for what you're doing with external reservoir 2.5 shocks. I think an OME monotube setup would fit the bill better imho.

Having said that, my ICON CDCV suspension has about 30,000 miles and two years under it and I have not had to rebuild any of the shocks yet. A significant number of those miles have been off road in harsh conditions. My rig is also extremely heavy which tends to make things work a little harder and wear out quicker. Will I have to rebuild these things? Yes, but Im pretty confident I can get another 10,000-15,000 miles out of them before that.
