Thanks for the replies fellas; I have been persuaded to go with the track ends, which was really my intial feeling.

What are you thinking here? Going Aluminium or -?
Firstly, not track TT, road time trails - fixies are quite common in the local clubs for TTs, espcially the 10 mile, my fave, and currently done on a bodged fix.
I was thinking of something with angles like 73.5 degs. HT and 75 degs. ST, probably with a head tube length of around 11-12cm for a 57cm frame (possibly effective - sloping geometry
may be used, I've not decided yet). I may use a set-back seatpost for the road riding, to bring the angle back to something like 74 degs, again another option.
As for the material, well to be honest steel, either TIG'd or fillet brazed - I doubt (and don't really want) lugs will be available for the angles that I'll end up with. My local builder (Steve Goffs, of Upholland, Lancashire, England) uses both Reynolds and Columbus tube sets, intial thoughts were of 825 OS main tubes with a 725 back end. I was thinking of having stainless steel track ends, with the tyre (23mm) about 2-4mm from the ST with the wheel at the front end of the slot.

It's got a low, low BB like all the road frames I ride, so it's STABLE yet still fast-handling due to the parallel 74-deg angles. It's got TWO bottle cage braze on for my long rides,.... well, you get the picture.
What can I say, looks great and looks pretty similar to my desired outcome! I too will be going for about a 58mm BB drop, though possibly down to somewhere between 40 and 50 to allow me to use my 172.5mm cranks, and eek out every last drop of power for the TTs
I may go for the rear brake (fitted stops and drilled bridge) just to keep my options open.
Thanks again for the replies, Olly
