I'm almost strictly Gyro right now, and I never really clicked with the Ion either, at least, driving it, so don't let that hold you back.
Try the Envy, for me personally, it's the Gryo Ring of Power, "in the darkness binds them." (In my mind, I kind of include the Proxy as a sub-mold of the Envy, since it feels almost identical in the hand, and flies basically exactly like you'd want your beat to crap Envy to fly.)
The Motion is great, too, one of the better beef-OS drivers on the market, imo.
Crave or Fission Volt are both good ones to try as far as neutral drivers go. I find these to fly pretty similarly in the 300-350 range. Little bit of turn, little bit of fade. I prefer the F Volt for a couple of reasons, but either would be good places to start with Gyro drivers, best molds to adjust off of, IMO. Maybe the Plasma Amp too. Everyone here seems to really like them, I just don't have one yet. Hey, that reminds me...
