I was never a fan of Q. Too glossy, not absorbent enough. Made a right mess of my behind.
On the downside, I read it quite a lot as it was often the only music mag on sale at airports and such like.

5kg is nothing for me, but I'm a big lump.
If you otherwise love the instrument and it's only your back putting you off, then why not try one of the various hip strap systems out there?
George Harrison's Cheer Down. We've decided to add it to our set list is a nice, bouncy, easy listening song to open with. That's fine by me as George is one of my musical heroes and I love the song.
You've tried the middle ground, and for whatever reason that isn't helping to resolve the situation. Send it back for a refund and start again elsewhere.
