Curved vane spider

I'm looking for a source for curved vane spiders, anyone have any suggestions? Has anyone changed from a standard 3 vane spider to a curved vane spider?

Craig, I tried sending this out earlier today but looks like it didn't go through. I originally made curved spiders for my scope and later decided to try a three vaned string spider using super thin archery string. After six months I still didn't like the diffraction spikes so went back to curved.

I think the bad press on curved spiders is that they traditionally had to be made from fairly thick material to support properly, especially when apertures got above 8" or so. My scope is 12.5 but I made the vanes from carbon fiber, pressed in a wood mold so they come out to about .04" thick, probably thinner than most commercially made four vaned spiders. I don't, however know of a source for any curved spiders.
