I had similar problems when I got my SS (Although I don't own a TWGS).
I have a ZipGS, RamFAST, and SS. When installed together my IIgs would
crash. Installing any two of the three would allow my IIgs to run
stably. The consensus here on csa2 was that I had too much line noise
running through my system. The cure was to replace the power supply
leads running to the motherboard with 12 or 14 guage wire. Also, I ran
wire from the GND connector on the slots 1, 3, 7 to the GND connector
on the motherboard's power connector. This did the trick (although I
can only run my ZipGS at 9 MHz instead of 12 MHz).

An alternative to this course of action may be to invest in a "Buggie
power supply". I don't have one (yet) but these power supplies may 
have reduced line noise and may cure your problems.

Good luck,

Paul.
