Landed spike-kenflip-spike
I'm not sure exactly what trick you mean by this. Do you mean...
1. Spike (Tomeken/とめけん)
2. Throw the ball off into an Earth Turn (Chikyuu Mawashi/地球まわし)
3. While the ball is turning, throw the ken 360 underneath it, straight back into your hand . = Whirlwind (Tsumujikaze/つむじ風)
4. Finish the Earth Turn with a catch of the ball back on the spike.
?
If that's what you mean, then it's a
Spike > Whirlwind Earth Turn (Tomeken > Tsumujikaze Chikyuu Mawashi / とめけん > つむじ風地球まわし)
I just tried it, and it's HARD, so if that's it, well done!
