Hey Jim,
here is a tip...actually thats what i do with my models... might work for u too...
when i m down with the modelling completely then its time to texture it...so what i do is that i delete the smooth proxy created by CPS...and then i take a duplicate of the half side of the model (low poly cage) and combine it (polgons > Combine) then merge the vertices of the center line...so now u have a final pologonal mesh...then i texture it the way i wana do it....using polgonal texture mapping tools...and in the end u can either use Smooth or can convert it to Sub Dz...
hope that might help...
Ciao
