Be rather expensive to add neos, and cheap but expensive ones no thanks. Have 2 OSB cabs and 1 plywood. Dont care either way. Sound mostly the same.
I just tilt it back and push, nothing to carry. Rather have one cabinet opposed to multiple cabinets you have to carry. After about 10 years the wheels get worn out. The only annoying process to go through replacing them. The vinyl gets shredded from loading, first one bothers you 10 or 15 years later, Dont care.
I have one favorite cab, it is OSB you can tell I use it the most because the sides are shredded. Not a real way to explain the difference very subtle.
Being a complete Ampeg expert I can tell you it is black and has 8 speakers. likely after you get use to it, wont really care about any other cab.
Good to have 3 of them, just to say you have 3 and then leave one at practice, toss one in a vehicle for shows. Then a 3rd one for no reason but can plank it in your bedroom or practice naked stage dives into bed. Or just take 2 to a show and let everybody know, why you are the headliner.
