I decided to go with the Studio Projects C4's. Mainly because it seemed that I was getting more for my money. The Studio Projects C4 have a built in base roll off switch, they are a matched pair, includes a nice carrying case, shock mounts included, and wind screens. Plus with all the "dead on arrival" Oktavas I had heard about, i didn't want to chance it.
I havn't had a chance to record with them, so until then, who knows if I made the right decision. I will tell you how they do once I get a chance to try them out.
