CB750 / CB750F1 Carb. Balancing ....

Hi all. Last year I got a carbtune manometer setup (with metal floats rather than mercury...). At that stage I had 2 goes at using a carbtune setup ... initialy got it running pretty good (with a friends mercury setup) but felt that one carb was a bit out ... so had another go with my own metal float setup (shouldn't have bothered). Managed to get the balance levels better but in doing so the idle speed is now higher than it should be...
My questions ... is there an order you should balance them (like ... 1&4, 2&3 ...)? Does it matter which carb is the one you set the others to? I am aware of the need to balance once all the other bits are checked ... oil, air filter, plugs etc. I will have to reset the throttle linkage stops anyway as they are now quite a bit away from standard... Last question ... is the metal float carbtune unit as good as the mercury unit(the reason I ask is that the first time I balnced carbs I used a friends mercury unit & 2nd time I used a metal float setup that I had accquired...)?
