The 'tri metal' aluminum carrier/Ti rivets/steel tooth sprockets look kinda neat (if you like that cheezy orange anodizing, anyway), but offer essentially zero 'performance' benefit (as they claim) vs. solid steel - but cost 2~3x as much. I have considered picking up one of the TI sidewinder sprockets for the marchesinis on my GSXR since steel sprox aren't available for those.
