The Community of Disc Golfers and About All Things Disc Golf

When Dave D. was around. Still might be? Then he could have answered this question. Heck if any one can, that would be nice. Soo, anyway. I had mentioned that I noticed I get about an extra 15 to 20 feet more "D" when I used Star plastic. He said that it infact is true, and that I wasn't nuts. Well, he didn't say the last part (about being nuts)because he would be wrong ;)
Now it's bugging me. How could a plastic that is not that diff, from Champ plastic get you that much more extra "D"? Now what I mean by "not that much diff" Is that both are smooth. So I wouldn't think Champ would cause that much more drag? Any one out there know or have an idea?

Star gives you good grip. More grip may increase "D" For some people
The Innova website claims that the Pro-line discs have more glide than their other lines. Don't know why, but that's what they claim.
I happen to think that DX plastic flies the farthest, it has the best grip period and I think that the roughness of the plastic works kind of like the dimples on a golf ball. Heres how it works with them.

"Dimpled golf balls fly much further than smooth balls. Before discussing why this is true, we need to understand something called the boundary layer. The boundary layer is the thin layer of air surrounding a ball as it flies. In the boundary layer, the speed of the air varies from the air on the surface of the ball (which is not moving relative to the ball) to the air out by the mainstream airflow, at the edge of the boundary layer. The reason dimpled balls travel further than smooth balls is because the dimples on a golf ball create turbulence in the boundary layer. This actually helps because the dimples then scoop air back towards the rear of the ball. By moving more air to the rear, this helps keep the air pressure behind the ball from dropping. And by doing this, the amount of air pressure pulling backwards on the ball is decreased."

I think DX works similarly to the golf ball dimples but this is outside the topic. I happen to think that star and champ fly the same distance sometimes one goes farther and sometimes the other does, I can't really find one consistently outperforming the other I like both and I use both. The grippiness and ability to put more snap on the star plastic because its grippier seems to make sense. It would have more spin and stay stable longer.

Its the grip of the plastic polymers... Gives you more snap which creates more spin thus giving more glide... simply put
This is a very interesting topic that I wish more people would get involved in - long time pros and maybe some of the peeps that actually make discs. I really like to understand the science behind things I do - maybe it is just the geek in me. If memory serves me a DX Valkyrie has the current world distance record of 820' (never saw what the weight was - I assume 150 class?). Some of the points made seem very logical and convincing but I'd still like to see hard evidence.

I'm not sure that getting (for example) a Star Boss and Champion Boss of the same weight and relative run would be a very decisive factor. From what I understand the molds can be slightly different which can effect flight characteristics as well as the different plastics - meaning apples to oranges. I guess one thing that "someone" could do is get 10 of each disc and throw them over 100 or 500 times and see what the end result produces.
I seem to get better distance with ESP than Z. I think it is a combination of better grip allowing you to throw with more snap, and a difference in stability at the end of the flight giving it a little more glide.
Dave M. [owner of Gateway] says the thing about better D with DX types of plastic has to do with microporosity. All plastics are microporous, or have tiny holes in them, at a microscopic level. If the holes are the right size to catch individual molecules of the gasses in air, those molecules spin like little ball bearings on the surface of the disc, and then it is like your disc is rolling through the air rather than sliding through the air.

So I guess before throwing a DX disc, you should blow on it to load up the micropores!

The first part is what he says. He may be right or wrong. I don't know.
