Tim, the limbs of a CLX are the same limbs as the LX. However, since RER's are made by hand and not CNC machined, the limbs are not necessarily interchangable between risers. In other words, the limbs are made to fit the riser.
A new set of limbs can be made to fit a specific riser. Making a new riser to fit an existing set of limbs can also be done, but we really don't have them priced out that way at this point. If you seriously would like to look into the possibility give me a call.
The bow pictured here is just the second one out of the shop for the new series. I just listed it in the sponsor classifieds this morning.

The "C" series sure seems to have generated some interest, so will likely see more of them coming out for the in stock inventory and to take to shows this summer.
