Keitht,
The basket throw is the old fashioned between the legs granny throw, like we used to do as kids with the basketball.
All great points BTW. consistency is the key as blinky said. It is nothing more than a shooting sport and all shooting sports require some fundamentals:
<ul type="square">[*] stance
[*]aim
[*]release
[*]calling the shot
[*]follow through
[/list]
Work on making those consistent shot to shot and your percentages will increase.
However, like with every shooting sport some days you are in the zone and other days you are not even in the same solar system.
We have a 6 shot policy, if you ain't in in six, hand it over to someone else. More often than not they will get it in the first try. Dunno why that is but it works.
For practice use a short tree with tiny limbs and aim for particular crotches. We're talking something like a Jap lilac, crabapple and the sort. You won't have miles of line to flake and you can work on your aiming, timing and other stuff. Get that muscle memory into your body then practice on higher stuff.
A couple of priciples come into play here the most important of which are the mechanics are the same but the chance of success is greater. With more successes under your belt the more likely your mind will get into the zone with your other shots. it's just like teaching kids archery..get them on target as soon as possible even if it means putting it 10 feet away!
FWIW Seldom do I practice on anything higher than 30 feet.
