Front wheels, OTP lacing?

it's mainly (I think) because for OTP, the builder can't really tell in advance what type of rider will use the wheel. (S)he could be 60kg or 160kg. Also to a certain degree, the builder can't dictate what the wheel will be used for. I could buy a bianchi pista and use it to commute, or track only.

but really, 3 cross 36 spoke on the front is a bit excessive sureley?

not even butted spokes. These fakengers on brightly coloured deep v's pay over the odds for a wheel they think is good, and suitable for track.

When really its more like a mountain bike wheel, a heavy one at that.
