G7 feedback for a 707 user...volume related

[Tubesteak 1]

Currently in 707 but, like many have said, feel the heel and depth are a bit big. I solved most of the volume/depth issue by going narrow instead of regular (which I usually order in Graf) and throwing in superfeet. Actually these are my most comfortable skates with the clarino and nice padding. Any feedback on going from 707 to G7 in terms of how much narrower the heel is and the depth change? Wondering if I should order Normal in the G7. Not looking forward to the airnet liner btw.
