Not determining, but essential if you want the most skipping potential. A plastic that is slightly less susceptible to friction will skip better than one that is more, all other things being equal. Kinda like shaving every bit of weight on a race car so it will go faster.

Agreed, but from my observations, firmness trumps slickness. That is why I get so p!$$ed off when I order an over-stable disc and it comes in a flexible plastic. Maybe forehand dominate players might want OS and flexible, but I find it useless backhand.

i just throw the discs

Exactly. The amount of surface area that a disc touches the ground on a skip is small, especially if it a P/A like the Zone or any other gyro. That is why nose angle, speed, firmness of the plastic, and the ground surface have way more to do with the actual texture of the disc since only about 1.5cm is actually touching the ground. It might be that since the gyro rim is weighted more it leads to less force going back into the disc when it hits the ground.

^Entropy skipped pretty good in that vid...

Hey if anyone thought "**** I wish they made a 180g Proxy" then a heavy Vertex may be for you. Very cool long turnovers, I wish I had more space on my downhill driveway shot.. I think it was comin back.

Played a round with it, decent.. Everything I like about a broken in Tangent +10g. I don't know why I never clicked with the Theory... or the Proxy... it will give me better separation with my Spins.. The 174 was too redundant.

You know what another name for Proxy is?

Alias.

If you want a 180g Proxy, that's where you can find it.

No **** eh? I thought the Alias was more Buzzz kind of stable.. Maybe that is Proxyish.. I hadn't tried one of those yet. Probably a better option for most than a Vertex.

Yeah I'm not recommending people go out and buy a Vertex the general consensus is they're goofy. I like goofy discs.

Never thrown a buzzz, but bag an alias. It's just an absolutely dead straight disc. In my set-up, it's my longer anode. No turn, no fade, just dead nuts straight.
