Hi Jez,
this will be scratch build #2 I presume?...............very nice job sir!
I have read about and used superglue, not sure how good Titbond(?) fnar fnar,(Titebond) or epoxy is, but like yourself I did a fair bit of reading up on it beforehand and ended up just as confused.
It seems everyone has their favourite method and they all seem to hold the frets in well enough.
I decided in my case that as it was my first fret job I would use superglue and do just a few frets at a time. It worked out quite well and the only thing I will do differently next time (and there WILL be a next time) is to try the pre-bent fretwire which comes ready cut.......I found it a right pain bending it to a consistent radius.
While I'm on, the build I'm just about to start on features a lot of wenge.......a wenge neck and fingerboard.....did you cut the fret slots on your neck yourself, if so how did it work out....any tips as I've read that wenge is quite splintery but worth the effort in the end
good luck with yours
Harry
