Ah, nice looking. Looks like the center holes are dished, which is different from the Contour one. The Contour one from Fidanza comes out to 9 lbs (plus or minus 0.2 lbs, according to my scale), while the SVT Contour one came out to 19 lbs.

I've definitely stalled it a few times already. It's going to take some getting used to, but it rev's up and down very quickly. The tradeoff is definitely worth it.
