That video is retarded. They are comparing an expensive (~$17 on DGCenter) X Link discs to discs that are generally $6-$7. How about they compare it to an HPP Evo Wizard or Star/Champ Aviar. Does the pure come in Opto?
Also, putters get good after they beat in. Wizards are made to beat in and if he would have shaped it back with his hands it would have been flat again.
Either way, bad testing.
As for the OP
Your flick sounds clean if you can flick a pure 250ft. I'm guessing you had ultimate background, most ultimate players can flick better within about 300. Get a disc with a bead, it doesn't need to be premium plastic and in fact should NOT be premium plastic. They do not glide as well, and that fact alone goes against your flick style. Flicking a putter takes a lot of spin, less velocity, and letting the disc glide.
Beaded putters last much longer than non-beaded putters. The favorites of those would be a big bead aviar, and my favorite would be gateway putters. A wizard for you would be too overstable right off the bat. A voodoo or warlock might be what you are looking for, but in the long run you will want a beat wizard for stability due to the bead.
Another choice would be the ion. From what I've thrown they are pretty stable and will stay that way due to the plastic/rubber they are made out of. They are more expensive but have tons of glide and enough stability to hold a dead straight 250ft shot +
