Cool. From the the replies it seems like I may be on the right track.
I'm using a sort of fan/control grip hybrid where my pointer finger rests along the rim, thumb toward the middle and the "rip" point is the base knuckle of my middle finger(second from the palm). I get a pretty clean release with this. I've been working on a standstill annie shot lately with the goal being that the disc fades out and starts to slip backwards ( from the nose up) right at the basket. It's really beautiful when it just seems to pull itself up, put on the brakes and hover gently down into the cage.
It seems to work best with my floppy aviar PnA's. (Of course I can only hit it 1 out of 20 tries.
The pull of this shot for me starts with the disc below my waist with the nose pointing at the ground.
I bring my arm up and whip it out on the intended arc right at the end.
I seem to get better control of the power I want this way. if I try to do a "straight" pull I end up spraying wildly and have no control over release angle or power. This technique doesn't work well (yet at least) for flat or hyzer.
I'll try to work on a straight pull. I guess that like driving, you need to minimize variables and learn to make 1 technique/disc do everything.
I've heard that a whittler is good for this type of shot and am considering picking up one.
Any other recommendations?
