i'd say it depends on what you want to do with your bike. you've most likely got a wider Q factor than typical track cranks, your cranks arm spider is going to have a smaller BCD, you need to find the right BB for a correct chainline and (not that its a huge deal, but) they'll weigh more.

you'll have to put in a little more energy to sprinting and general faster paced riding, and larger chainrings on smaller BCD spiders have a greater potential for warping.

but they'll probably be the last thing on the bike the break, and the chainring selection out there is pretty rad.
