also depends on what you're using it for - is it track or slave? brakes or no brakes?
...rc-540's don't have much in the way of braking surface iirc.
When I was building my track bike I just went for Open Pro's in the end: Araya and Ambrosio were comparable weight/quality-wise but more expensive and less readily available. tb-14's are quite heavy and wide, which is good for town but not great for racing. The finish is also much shinier than the silver Nitto stuff.
