Different plastics affecting flight characteristics

I had a DX wraith that flew very well for me, especailly as I got better.  After a few hundred rounds, it got pretty dinged up and even had a hole in it.  So since the wraith flew so well for me, I thought I'd upgrade to a star.  But my star does not fly the same way.  It sharply curves the movent it leaves my hand instead of just at the end like the DX wraith did.  Now I'm having the same situation with my pro katana.  Should I upgrade to a star to mitigate the damage it sustains or buy another pro?

I picked up a Z Buzzz SS shortly after they came out and it is more like a Wasp with a splash of Buzz in it. Then a couple of my buddies have picked up there own since that time and they are like a nice wore in Z Buzzz. It all depends on the mold method if you have success with a disc of one plastic go out and pick up afew and hold onto them.
