the double or single is my last ditch effort lol. There was this guy today at judo who was strong as hell (he came in second for the olympic trials this year for rowing, but I didn't know that till after judo). He kept pushing me forward on my uchi mata so I just went single leg and slammed the crap out of him. Felt so bad about it cause he didn't get up for like 3 mins. I really only go for it if I'm desperate lol. The only other pickup I do is te guruma, which works great, but expends tons of energy if they turn over onto their front. I have to get out of the habit of grabbing pant leg instead of leg though.
