FSA chainring question

I have a FSA Energy ISIS compact crank and the rings are getting
worn, especially the big one. I can pick up a newer FSA Gossamer
megaexo cheap enough which has much cleaner rings, cheaper than
buying new rings. Are these the same rings?

thanks, Rick

A quick look at FSA's website shows that no, they're not the same
rings. the Gossamer rings have traditional cutouts, while the Energy
rings are CNC machined to thin the edges inside the spider. I can't
say which is better, but I prefer the look of the Gossamer.

The older ISIS Energy crank I have has the non-machined type rings, they
started the machined edges with mega-exo version of the Energy crank. I,
like you, do not like the look of the machined edges. thanks.
