Excellent subject tho thread starting question is a bit open to interpretation.
Gyro--I think if that's your criteria for PB purchases you're gonna have a mighty small selection to choose from. Not that I'm in any way defending the Gardners, simply noting they are the perhaps the highest profile offenders but hardly the only ones.
Anyway, the Ion is gonna change the marketplace and do it in two ways. 1) it's straight competitive where it counts--on the field. A few teams, including Miami Effect, were using some Ions in LA and they performed well. In a 15 bps capped universe they deliver. 2) it changes the concept of the customizable marker. Instead of paying three or four times as much for a marker you plan on adding "necessary" extras to you can begin with an Ion instead. And wait until somebody starts producing designed and anodized aluminum shells for the Ion instead of plastic.
Further the niggling sorts of failures that drive you nuts in a $1200 gun don't seem quite such a big deal in a $280 gun. Now if SP would only build a decent detent . . .
Seriously, this gun is gonna force makers to come up with new, better reasons to spend $1200 on a gun than they offer now.
