I don't throw much innova anymore other than fire/thunder birds (although my destroyers always had a big variation between the plastics) but with any company, depending on the plastic their molds will fly differently.. but then even colors sometimes mold up different. I prefer to always buy the same colors (red, white or blue) in all of my molds/plastic and i don't notice much variation from run-to-run.
I throw mostly Legacy at the moment and i have found...
Ghosts in gravity are much straighter out of the box, whereas Icon will have more fade and typically pinnacle will also be more overstable, and certain colors are just tanks.
Rivals in Icon are straighter and hold lines longer before fading, whereas i find most of my Pinnacle fades earlier, stuff like gunmetal Legend will be the most over-stable
Patriots in Icon start off very straight and hold turns longer and pinnacle starts off just slightly over-stable and resists holding a turn or going into a turnover as easily.. some of the Legend i have tried is also more overstable.
Outlaws in Icon are truer to the -1 turn rating where as legend will start out straight 0 HSS and resist a headwind more.
Rampages and Cannons have the most variation because they are such a high speed and that leaves a lot more room for error in the process.
Generally I know that Gunmetal Legend is the most overstable option in their molds, followed by Silver Legend, then Pinnacle, Icon, Gravity.. but there are exceptions between colors and runs sometimes
