I stand by my comment on using ti bolts there. Titanium simply galls and stretches way too easily for a situation that requires frequent reuse or high torque. That's even a worse use than in stems or rotors (which is utterly stupid and pointless).
As for jackstraw's issue, It's most likely not a locktite issue. Even red locktite won't seize that completely. Something had to have totally buggered the threads there. If they are ti bolts, they could easily have been over-torqued which can stretch the threads, causing the seizure.
Personally, I want the strongest bolt I can get for this application. I don't even like stainless here. Just good solid steel.
Adaptors? Sure use locktite blue. They are set & forget.
