I had someone ask for clarity on these transitions on the 10th Planet Rochester training blog, so since I got tattooed Friday and couldn't train yesterday I decided to take pics of the transitions while Scott and Huan where drilling. I thought I'd share it with you guys as well.
The Reaper to Calf Crush/Knee Compression:

Step 1)Scott dives into the X-Blast position on Huan.

Step 2)Scott lifts his hips and knees forcing Huan to stand, Scott transitions to X-Guard.

Step 3)Scott transition both hands to hug Huan's left knee for control on the near leg.

Step 4)Scott pummels his right arm through to a over hook on Huan's left leg, still hugging the knee.
