AE has said (in their America On-Line product support board) that they
have no current plans for speeding up the TWGS clock beyond 7MHz.  This
may be partly due to the unavailability of significantly faster 65816
chips in quantity.

I installed the TWGS cache upgrade and noticed the improvement in
effective speed for many applications.  I can't help you decide whether
to upgrade the TWGS or replace it with a ZipGSx.
