I just ordered a Roubaix Expert SL4 Di2 (in my size) It should arrive tomorrow or the next day! I've been reading a few reviews about the DT Axis 4.0 Wheelset. They seem to be average at best.

I don't know if I can get any trade value for the DT Axis 4.0 Wheels from my LBS before I take the bike? But if I can, would it be worthwhile to upgrade the wheels now and what would a modest, but worthwhile upgrade be??

I am an semi-experienced recreational/fitness/group rider. (Mostly group rides, endurance rides, some climbing. 200lbs)

What wheel set do you recommend that would be better than the DT Axis 4.0, but that won't break the bank?
