Which BIG BOV to buy?

Hey guys I am in need of a new BOV, a big one, my little pos greddy type isn't cutting it. I'd like to hear some feedback before I dump some more cash into the money pit.

Tial 50mm, average $275.00 with weld on flange
Godzilla, average $320.00 with weld on flange
Vortech bv57, average $375.00 flange extra $25

They all look like they can work for me, so why should I spend my money on one -vs- the other? Does anyone have these or are there other better pieces I don't know about? TIA!

I like the Tial. I've only used it on two different applications, but it worked great. The most recent application was an Edelbrock turbo kit I installed on a '99 Civic Si B16A2 running a Garrett GT28R. FOr some reason the turbo surged during shifts when the kit was originally installed. By the time the customer came in a for a 300mile check-up, the BOV was working perfectly (can't explain that one).

I have no experience with the others.

I like my Tial, it made the belt squeeling go away while shifting.
