I'll have a go.:)

1. keep the cover simple but cool, like some artwork that overfiend sugested. (dont clog it up with to much text like M8 or those types, enternity worked on this format if i remember, it stood out))

2.The Bonus CD idea sounds brilliant..

3. I think the limiting the styles would work against the magazine(already a lot of competition)

4.Some tech pages for equipment and stuff.

5.Quality over quantity.
