holley or edelbrock?

i realize that i have to tinker with the setting but what i don't know how to do is to mess with floats and changing jets and any of the other stuff that i consider more in depth. I am leaning towards the 770 avenger, it sounds like there may be less hassle. anybody use any of the avenger carbs?
I bought a new 670 Street avenger for my truck's 360. I didn't like it at all - I had a real tough time tuning it in. It also idled like crap. I replaced it with a rebuilt and tweaked '73 thermoquad - the engine now purrs like a kitten and screams at WOT. I also have a 750 Edelbrock performer carb on my Charger's 440 - no major complaints with that.
