953 or Ti?

As far as I know yes. Last time I checked was 6 months ago when I asked for my new bike to be fully 953 and was told that the forks would have to be 753 as Reynolds had not made the tubing available for 953 forks.

Dragging this up from the depths of time to note that there are now 953 fork blades, apparently http://road.cc/content/image/18270-reynolds-953-fork-blades

Haven't see a 953 steerer yet, but I'm guessing if they go to the trouble of making the complex fork blades, the relatively simple steerer would be a no-brainer.
