Wade,
You can eliminate the possibility of the choke being the problem by setting it wide open first thin in the morning when cold. That will keep it open all day long, If it solves your problem you know what it is, if it doesn't solve the problem at least you've eliminated the choke as the culprit.

My Edelbrock is manual choke and I just wired it open.

Your cruise should just be on the primaries, as long as the secondaries aren't opened with a lead foot, so the secondary metering shouldn't be your problem. Calibrate that after you get the Idle, transition, cruise and pump circuits good.

I'd start over with the idle mixture. First make sure the float is adjusted correctly then set your idle speed, adjust one needle for the highest rpm and vacuum, readjust the idle speed and tune the second needle. Keep adjusting both mixture screws and idle speed screws until you have them set so adjusting the mixtures produces no increase at the desired idle rpm. Then lean out additionally to get a slight rpm drop. That will be your best lean idle condition,

As far as the springs, try a little lighter one. You want the vacuum signal to keep the rods in the lean step until you have a higher load. If the spring is lifting the rods too early you will get a rich condition. I don't remember what strength of spring is for what colour. If that doesn't help or you have power circuit problems you can always change them back.

Just thinking out loud here, hard to help much not being at the car.
