I like the colour scheme... looking good! :-).

For me, as I was going 700cc, I replaced the front fork completely with a carbon/alloy version designed for road bikes. That saved a lot of weight and improved the ride (carbon reduces the vibrations from the front wheel). The fork version I used was this:
Wiggle | Columbus Tusk Carbon Fork | Forks

Columbus also do trekking versions of the fork (with V brake fit points) if you want to keep the 26" wheels...
