I have the HQ avante which is not a mid arm but an 18" long arm. I bought the studio frame with it which can be set up at 8' or 12'. I have it set up at 8' and so far it has been plenty big enough for me. I knew if I bought a mid arm I would end up wanting something bigger but didn't want to go real big so I got the Avante and am so happy I did.
