full band/limited adda

[sadworld]

i've been using 16in and 16out so i've never had an issue but i'd like to upgrade my converters to high end stuff... maybe rosetta 800. i can only afford one at the moment. just wondering who records a live drum kit and gets by with 8in and 8out adda? how do you work? do you premix drums on the way out to your mixer? usually i'll need the 8outs for drums but i'm just trying to see if theres a way to make this work... can i do this upgrade and still be able to work....if theres a way around this i'm not thinking of, please share. thanks. matt.
