Hey,
Thanks! I did speak to Scott about his mod but decided to keep it standard for now. It makes a good companion for the Novatac, which I just received the other day.

Buffalohump, nice lights.  Milkyspit (Scott) over on CPF does a wonderful Seoul P4 mod on the HDS.  My Basic42 is a whole new light.  Of course, if you're into modding you could do it yourself, there's lots of instructional threads.
