This has been a good task for me to understand things better.
I think a new thread for BLAKE_T would be :What I have learned from DGR.When something clicks for you feed your knowledge to him.
ROUGH DRAFT 2 (It takes me a long time to get a final revision)
Slip vs. Rip : The point of contact and the drive
98% of disc golfers have slip on nearly all of their drives (except for on grip locks).People that max out ~400' still throw this way, with lots of slip. The disc slips out on pretty much every throw but they have practiced their timing and positions allowing a slipped throw to come out straight. This is why you see some guys who peak at 380' straight but can grip lock 450'. When they grip locked it they actually hit it.
In baseball (and golf), there are hitters that SLAP the ball and hitters that DRIVE the ball. A hit that is "slapped" is where the ball bounces off of the bat (or club) after contact. These generally don't have home run power. a hit that is "driven" is where the bat makes contact with the ball and then the hitter releases his wrists, causing a huge acceleration of the bat (or club) head and the bat head will fling the ball off the bat. Basically, a slap has very little force imparted on it .The bat redirects the ball. a drive has high levels of force imparted on it. The bat stops the ball and then pushes the ball. This is the same for golf.
The only time when arm speed is of any importance is AFTER the point of contact.
The point of contact in a disc golf throw occurs when the disc enters the power zone, which is
when the disc reaches the right edge of the body. The disc should be close to the body. The wrist is usually curled and the elbow is at its maximum amount of bend here .This is the point of contact. The arm/disc must accelerate immediately after the point of contact. The release of the bat head is the tug that follows, uncoiling the elbow and launching the disc. This is how you drive a disc (throw with snap).
430' with a Teebird is big snap.
430' with a Destroyer is not big snap
What happens with the disc/arm during the final 12" of the throw is exactly the same for everyone throwing 500'.
THE POWER OF THE THROW HAPPENS AS THE DISC PASSES YOUR BODY AND BEYOND. To throw really far, you must throw really hard. Knowing when/how to deliver force is the key of this. Most players decelerate entering (and through) the power zone and the end result is a slip (even if it goes straight and decently far). Hitting it requires acceleration through the power zone. As you get closer to the rip, your hand (and the disc) must be moving FASTER than it was at every point before that. You have a better chance of hitting it if you enter the power zone at 30mph and reach the rip at 40mph than you would if you entered the power zone at 60mph and reached the rip at 50mph.
The difference between the wrist in half-hitting vs. full-hitting is:
With half-hitters, the wrist extends because the inertia/momentum of the disc forces the wrist open. It's basically a half-slip.
With full-hitters, the wrist extends actively and accelerates the leading edge of the disc to a VERY high velocity in a very short period of time.
What you are looking for is to transfer the force caused by the change in velocity of the part of the disc that becomes the lead edge as it whips around via wrist extension (the angular velocity is huge).It basically goes from like 0 to 100mph in like 4" of wrist movement.
Basically, your goal should be to exert force on the disc. If done correctly, spin will happen.
Remember that this feeling is part of a process. At first you feel the disc pulling against the fingers, the second stage in the process is to feel the fingers pulling back against the disc and slinging it forward. The lock leaves during the pivot and the last thing you should feel is a slingshot off the index finger.
The difficulty in timing occurs because:
-the forearm/elbow must be relaxed at the beginning of the extension but should be firm/strong near the end of the extension.
-the wrist/hand must be relaxed at the beginning of the extension but should be firm/strong near the end of the extension (and subsequent release of the disc).
Something to be known about this is that if your form is missing the basic few fundamentals, working on snap is rather moot since you'll be blocking yourself from getting it and it will basically be an exercise in frustration.
Before attempting to work snap you should:
1. have a sound, fundamental grip (wrist down, etc.)
2. be able to throw with shoulder rotation (not everyone does)
3. have a pull line that keeps the disc close to the body.
4. have no problems with getting your weight forward (unless you are content only throwing
hyzers).
5. be able to throw without "strong arming" the disc.
6. be able to throw without jamming your pivot (aka allowing for yourself to clear the hip).
7. be able to throw without significant OAT.
Without those 7 things, you probably aren't getting 350'. without those 7 things, you will be unable to hit the positions/timing needed to adequately learn/understand snap.
You have to learn to walk before you can run.
