I don't know to be honest... I'll figure that out later.. Right now though I just need to order the 7000 wt stuff I guess, since I already have 10 and 3.. I know that's what people have recommended for the Muggy... So I guess, cuz I have to order soon, I'll just order some 7000 and live with 3--10-7 or 7-10-3 or whatever it is..
