[Supras] Need CT-26 core and modifier recommendation

[t72pwrd]

Bernie,

I'll send something more detailed tomorrow.  I went with a -60 and didn't 
regret it.  I just got back from a 12 hour drive and I'm too tired to type 
coherently or cogently.  All I want to do is drink some beer right now.

-Nick
