Cab4T,
I have the Cosmic on my bow and am shooting 3 spot Fita league and it IS TOO BRIGHT! With the indoor flourescent lighting I can barely see the ten ring. Not so much Halo effect as just a big diameter fiber and very bright pin.I still use it cause I really am only practicing to hunt. I would think it would be great for outdoor 3D....but I don' t know...haven' t tried it. The 3 pin looks like a nice sight too.

Silentassasin,
SME no longer exists. The guy that held the patent on some of their stuff has a new co. called Vital Bow Gear. They do have some cool stuff.
