I`ve tried several cheap verts over the years then hooked up w/Continental here in Calif. and never looked back. First was a 10" for my high 11-sec small-block which worked good but wasn`t ideal behind my 10.40 big-block so Cont. hooked me up w/the 8"5000+ vert I`ve run for 10+ years now and it seems to be working well but I havn`t tried anything else to compare it to.............lots of west coast bad ass street racers run the Cont. verts w/great success.
