Savage Flux Big Bore Shocks

I just picked up my Flux and I am currently waiting on my battery packs to come in. I put it next to a Nitro Savage X and noticed that it sits significantly lower. The folks who have been running theirs have you been pleased with, disappointed in or other wise with the single shock set up?

Other people around my local hobby shop, including my friend who manages the place questioned the single shock set up. You guys are always pushing the trucks harder than most so I am curious to hear your thoughts.
