Wotgtp

I'm shopping for a new one(preferably used of I can find one), and price wise it seems like a good deal. I assume Edelbrock made it for summit? They look almost identical. Anyone here use either? I'd rather have a throttle body that has a "smoother transition" in response, instead of one that you crack open 20% throttle and you feel like you went wot. I personally hate that feeling. On my setup, a lot of Gus like the LS1 TB because it doesn't do that, where as the northstar TB(vortec style) just dumps in air at light throttle positions. Any help would be appreciated, thanks.
