Question Holley or NW Throttle Body for LS3

I'm having a build LS3 dropped in my 2004 GTO. The LS3 has a stock Camaro SS intake (90mm inlet I believe).

I need to get a throttle body (cable driven) and a cable bracket. I noticed the holley comes with the backet and with NW I can pick up one for it.

I see a lot of people like NW, but what about the Holley?

Also, it seems most places I looked have 92mm throttle bodies. Would it be worth much to remove that extra 1mm material around the hole to match the TB to the intake?

Any sponsor that has a good deal on either, feel free to reply or PM me the details, thanks!

I've got a Holley 90tb on my intake, it's a quality piece and probably the nicest look TB I've seen. It does cost more than the NW 92, but I have no regrets getting it and the cable bracket works great. I modified mine for clearance and to smooth out the looks.
