AVS2 800 carbs

I have tried the Ede 600,650,750 performers on my car.
Out of the 3, the 750 I liked the least. Never could get it to run the way I wanted. Maybe your write up would help.The 600 comes in 2nd. Great signal, great throttle response. I would imagine the only thing you lose is at the very top end, which I won't do on the street. This leaves me with the Thunder 650. Seems to be the best of both worlds, adjustability, performance. Haven't had the chance to play with the AVS2 yet, like the theory behind it. If I did, it would be the 650 for a SB.

This is on my 360, fairly mild combo, Comp XE268.
