- Make sure your chainline is good.
- Check that pedal clearance on your track with your particular crank / frame / pedal combo is not going to be an issue.
- Be aware that you'll be less likely to be able to borrow chainrings from others to use on these cranks as they are 130bcd (I think). Most track cranks use 144bcd. If you have your own chainrings this is not an issue.
Otherwise, I'd say go for it. If you get comments about crank stiffness vs true track cranks I'd take them with a pinch of salt; this is almost certainly not an issue for you at this point.
