I haven't played a h/07 but my 070sr is hands-down my favorite 7 string. Maybe someday I'll have the patience to actually order one with a wild finish instead of pouncing on dealer stock.

abasis don't do this as well as you'd think. they don't balance that well in a lap because of the upper horn moving the center of mass forward. Get an Aristides imho
Some people don't love the feel of the Goliath. You've tried the M80M so you know what you'd be getting. Personally I'd go with the known quantity, unless I really wanted a neck pickup.
