I have a 10 sp FSA Gossamer 110mm BCD crank set. The rest of my drive train is Shimano. I want to replace both chain rings. I'm looking at these two:

One is made from 7075 aluminum but says it's only compatible with Campy. The other one is compatible with Shimano but made from 5083.

Are they actually different? What are the consequences of using the Campy ones on my bike. I wore out my last set quickly and want the better alloy.
