Thanks for the encouragement!  While I plan on attending the Summer
Star Party in the Berkshires, I'm not sure I'll be bold enough to try
shooting or developing Tech Pan while there....

I actually did this, although I didn't do the whole development
process.  Unfortunately, the only old strip I had was some Fuji
Superia and the thickness is quite different.  I loaded so easily that
I think I had a false sense of confidence.

I may switch to the water stop bath.  I'll also have to practice more
so I get the hang of the steps and can do it without thinking (too
much).
