I don't think it particularly matters what you use, grease or anti seize, so I vote grease because it's a little less messy.
Appreciate the input, and I'm just a newb with this stuff, but everything I've read suggests that aluminum will readily corrode when in contact with titanium in the presence of an electrolyte....they're practically at opposite end of the galvanic spectrum, according to the material I've read.
The anodization info is new to me. Thanks!
