Man, you need to do a search on Archery Talk about Rock Solid. They've had a lot of bad press lately about getting months behind on orders and some not filled for as much as four months or so. I've used WC's and they are good, but you can PM a couple guys here on this site and get strings just as good for quite a bit less money. One is MeanV and I think he handles Vapor Trail strings. The other is Gibblet and he makes strings under the brand name Bucknasty. Both have very good following and are noted for superb customer service.

I have not used Vapor Trail, but have and am presently using Bucknasty strings and they are of the highest quality. Every bit as good as the $140 WC's on my one bow.
