I came VERY close to nailing this move tonight against another blue belt of similar size. I got the insert entry, I grabbed his pant leg, he pushed forward, I grabbed his lapel and then I inverted. So far so good. I even loaded his weight correctly. But when I went to do the pendulum motion with my legs I was a little off and he was able to post a leg (thereby thwarting the sweep). But still! This is real progress. I think I need to pay more attention to the hand I hold his lapel with. If I keep that hand there during the sweep maybe I can use the grip to keep uke bent forward (and loaded)? Or if I release that hand I guess I need to work on a quicker set-up to the pendulum (before uke can posture and post a leg). A couple of things to think about. But as I said, I've made some head-way. More drilling.
Cheers
