Mount them, it will make them make a decision more next time, they'll start worrying about defending the mount instead of whats going on in side.
i'm not sure were your actual problem is, whether its the leg not coming acrossat all or not being able to get it to where you want it.
but my issue was i was hooking round the knee and couldn't get it, across they were still to strong. hook there ankle instead and draw it across with your ankle, i find it easier, they have less strength to pull back with, plus it leaves more of a gap, to shoot, my other ankle up to grapevine... once again not sure if this is what your looking for, but hope it helps?
