I'm currently using Bontrager race compact crank 170mm on my Redline Team.
Picked up a FSA SLK Carbon crank for peanuts but its 53-39 with 172.5mm (used that size for a long time)
Is it worth it to swap for the carbon crankset? An downsides? Just a little lighter and I'm not opposed to a little bling for fun. I'm riding my cross a my road bike now and migrated any of my lightest parts onto it.
I race recreationally, so am mostly on the road.
