Alternatives to pista/track cranksets

I think the Tooth Fairy works for the GPO- I've lost approx four teeth this year and had narry as much as a fifty pence piece left under my pillow.

My cash is probably in a Fairy sorting office awaiting re-delivery sometime in 2027.

I had four taken out last year. The irony of fifty pence per tooth would have been lost on me considering the massive bill I recieved :S

This year its fingers.
Broke three (on individual occasions) so far, and I've still got a few rugby matches, and a ski/snowboarding/snowcycling? season to go. On the plus side the Norwegian health service is free after you've spent certain amount that year.

As for OP. Track cranks have nice low Q-factors, and singlespeed cranks are lighter (massive generalisation) if they are purely designed for road (or maybe XC) use. If never of these things are of high priority to you then use what you think looks good and gives you a decent chainline (and does'nt interfere with the chainstays).
