There is a bit of Z in the mix, no doubt.
I have a pretty translucent Ti Wasp that looks like the Smoke Cryztal plastic Discraft has produced, with colorshift glitter in it.
But I have other Ti Wasps that are nearly 100% opaque. Some stiff Opaques, some gummy Opaques.
The difference in feel, rigidity, etc between these types is HUGE.
Stiff opaques is slick and smooth. Gummy Opaques are grippy and satin-feeling. Translucent is grippy and smooth.
Luckily, the FLIGHT between all 3 is pretty much identical on the Wasps. And they fly like a good Wasp should.
I do not throw buzzzes so I do not know if there is much variation between feel/fight as far as Ti goes on them.
