Yes I use Aggies, I remember about 18 months ago it seemed the cab of choice, so I bought 2 of them, they are really great cabs, its so nice to have such a compact loud rig, but still I think I prefer having more speakers. So like you said a pair of 2x12 Aggie's would be an ideal choice, but then the weight factor etc etc oh damn seems like I want my cake and eat it lol.
Maybe 6x10 would be good love the look of yours Dood or something like a Tech 4x12 being ultra light. I just never have found an all in one cab that has suited me yet, unless there is an Accugroove Whappo Jr floating about, now thats a cab I do like.
