I've had the edge and I'm on my second Katana. From you fleet I'd say get the Kat or the Fusion.

Edge is great for learning to hover and stability, the Kat 40 is much more maneuverable than the edge.

If you have the time and enjoy building I'd do a kit, with the upgraded gear.

BTW I fly my Accel Kat 40 with a saito 56, it has slow but unlimited verticle.
