Thanks for the feedback guys. Yeah I always go for scissor sweeps, they are a bit hard and you gotta learn to make it just one motion rather then just - take a few seconds to set up - then go for the sweep.
I've been working on them out of my long half guard with some (little) success but I still see it as viable. There are two people I roll with pretty consistently since they are around my size and level and both have commented on the sweeps.
I'm probably trying to make this work because my half guard is pretty strong and I like the idea of adding more elements to it. Especially those that will work without requiring any form of underhook.
