以下是給AJ的一些建議，我從Youtube貼來這裡，也可以參考看看!

Frankyueh:
Before you try to tap, you may need to know few things:
1. I think you need getting closer to the pallets before you jump up. Because you are jump too early.
2. Just try to touch the edge of the pallets when the moment that you are in the manual position. The touch not during you already jump up, actually happen when you are wheeling.
Hope these would help! :)
AJ:
thanks for the detail.
i'll try it next time.
do u have any suggestion height of the pallets for beginner?
if it happen when ur wheeling, is there a limit height i should be aware?翻車?
how about speed?same?
Frankyueh:
高度差不多就是你前緣放的那個棧板的高度，太低反而會練不太出來­。
翻是不太須要擔心，因為在Wheeling的時候不會太久，而我­也有注意到你踩跳跟我一樣是屬於半圈，和凱文一圈的有點不太一樣­，所以在前輪起來到撞的時間會比較短，通常可以告訴自己跳的過程­把身體放後一點，等前輪撞到的時候才有機會讓身體往前推。還有因­為你要撞前輪，所以起跳的距離不要太遠。
補充一下，速度唯持一樣就可以了。
你可以試著用一圈踏板的距離來嘗試，會比用半圈等待的還來得好。­
你先試看看吧!!XD! 期待你下一個影片能看到這個動作!! YEA!
