Yeah Dan, I'm actually going to be practicing osis> ducking/diving soon.
Tonight I had a session with Corey Gerges. He's starting to open big doors to bigger tricks. Stringing 3 guiltless the into tiltless. Hit a bunch of new stuff tonight: first diving osis, first flip diving clipper, first diving butter, first symp swirl, first gyro clipper, first double switchover, cleared a few really excellent Frantic sets (?WTF?).. He's been practicing and he's back into it for good now I think. Nice to see players come back from the dead.
I had a pretty uneventful session, only because I literally worked my Flip dives the entire time, aside from a few other experiments..
Highlights:

Pixie late Ingyro toe BSOS
Quantum late Gyro Toe! Very cool, first try, totally surprised.

So before today, my Flip Diving Clipper record was 5. I wanted to break that and hit 6.. I hit 6, wasn't happy, then hit 8, still wasnt happy.. So I decided 10 was a good goal for this session. Tried and tried and fixed my form and tried some more and fixed some more, then finally 8 became easy for me, out of the blue, I just was able to around 8 every time, then one run I hit 11, then accidentally weaved instead of dove (STUPID GUY) but I strung on 3 diving clips to the end of that. So whatever you wanna call that, that is my new Diving Clipper record. Will practice those some more.

Zulu Clipper (Red Ribbon) b2b is now much easier because of this practice.

Also, Pdx Torque> Ripwalk one side, first try, just to show Corey. Didn't try flipside.
Fun session. Work in the morning. Peace.
