To repeat notes from last time (I didn't notice them, as they were under americana rather than back take: hence why I'm putting both labels in this time ;D), one thing I could have added was blocking attempts to slip out the back. I mentioned that it's a common escape attempt, but not too much on the defence. The main thing I do is just grab the back of their collar to anchor my mount, then wriggle back to flatten them out (as they normally start curling their legs over to push into your armpits).
