Roy,
I started off going down the TLS route you have but as I'd just refurbed my A10 FW hub and rebuilt the wheels and forks - I decided to give in and sold the TLS. Julian kept me right and his information made it all clear. However not before I'd tried to sort out the brake cable! Consequently I now have about five (was 7 but cut up a couple trying to get the free lengths right). My advice is go with Julian's steer, even if you'r not intending wiring the front brake switch. Free lengths, fitting types, shackles, lever ends and over-all lengths are a minefield - best try to keep it simple. Ps - I had the brake lever with the built in adjuster which didn't actually help (and doesn't help with the 8" FW SLS). I also ended up having to extend the shackle end - so will replace it the second I find the right cable.
good luck. Looks like a cracking set up. Might be tempted to give it another go if I keep the A10 (been hankering after a new project but at the end of a work contract so on hold for now).
cheers Raymond.
