Haven't seen any Tebird3s in Metal Flake. Saw (and bought) a Metal Flake Roc3, also saw Katanas and Thunderbird in Metal Flake, but didn't catch a Teebird3.
Oh well, it's the TL3 I'd rather see in Star, Champ, metal flake, etc.
My local pias has MF teebird3's and a very sweet feeling MF Vroc so keep looking.
I have very dry hands so grip is an issue for me especially in the winter. I find the leopard3 to be stiff but grippy, really my favorite champion plastic. I did notice a stack of MF discs that were very slick. Maybe there are some slick leopard3's too.
