I can do a heel clicker over a table that launches you really high at a track near me, but that's the only trick other than whips. I can throw them sideways, but I cant lay it over unless I'm scrubbing.
The only way to land a trick is to first commit to it. As a precaution, make sure that you are dressed for the inevitable crash, but once you begin your approach, commit 100% or you will fail. With a little luck, you won't have to confirm the quality of the pads.
I was bored one day and started doing nac-nacs on a TTR125 over a 12 foot table top. There was not enough time to get back to the pegs, so I landed them 1 footed. I started with 1 footers, then no footers. Once I got comfortable with that I began throwing my right leg back farther every time until I got it over the fender. The end result was NOT impressive, but it did qualify, and it was fun.:)
