I'm not sure what you're looking for, but I can take a guess: when do you carve off a booter to clear it?
This is a pretty difficult feat, props to people who can do it (Took me a half season to find the sweet spot).
1) You're impressing nobody
--> 100 feeler hits > 1 season ending case
^pretty much the most important element with big booters. The feeling is the desire to showboat, even on the guinea hit. Try working past this.
Anyways, the best advice is to look at the lip and pop @ the lip. I've killed myself too many times from popping too early and undershooting shit. You can hit something with the same speed - straight line vs. carve - and undershoot simply because you popped too early.
Look 'where' you are carving. So many people (i was guilty) will look behind themselves before take-off, which generally results in popping too early (nerves). After a few hits, you will get the feel of the booter and be able to actually 'huck' blind, without undershooting; however, this requires a lot of trust with the booter you are hitting.
- at least, for me it does
