Anyone run a Street Avenger?

My main fideling issue is idle speed whih I know is my heat problem, too slow when cold too fast when hot.

Its an edelbrock rpm intake and TTI Headders 2.5" exhaust with x pipe. I have an FBO ignition box

The distributor was curved to match the engine by the shop that built it.

My main question I guess is are some of the cold issues just the nature of the beast or will a choke help that much?

Also I see a lot of debate about just when you should run mechanical secondaries.

When discussing carbs with the engine shop he also recomended the Edelbrock AVS Thunder over a street avenger but I never asked why, also he claims it will have better manners but will loose some performance again no reason to why.

I've thought about a thermoquad and been to Demon Sizzler's site and read the great love it or hate it debate but didn;t want to run an adapter on my square bore intake.
