I ran Icons (front resis & rear monotube, AP 3.5" springs) on my FJC. I'm running Radflo/OW 2.5s now on my runner (using AP 3.5" springs). Honestly, if this is your first lifted rig, you won't tell the difference. Even if its not your first it'll be hard to tell. Both are constructed with premium materials. One thing I do like better with the icons is how the front coils have less turns, which equates to less coil bind and less clearance issues, IMO. OW (2.0, 2.5) offer way better rear shocks in their kits, the Icon monotubes are crappy, constrution and durability wise. Icon offers piggy rears, but they're expensive, and honestly much more shock than you'll need.
Icons use 600lbs coils for the front, OW uses 700lbs coils for the front, which leads to a stiffer ride for a stock weighted vehicle. If you're not going to run steel/armor now or in the future, go with OWs 2.0 or Icons setup. If you're goal is increased ride height for the street, no sense in spending the coin for OW 2.5 or the Icons, since they are comparable in price. Might as well go with OW 2.0. Considering your application, you should also look at Toytecs adjustable coilover kits.
