First make you 2's a clean as you get them. Then just set the spin harder by scissoring and just spot your landing as quickly as you can. Once you land one of them you'll figure out that they aren't actually that hard to get around as long is somewhat off the ground.
A tip that really helped me for front 4's is to just quickly throw your lead hand behind your back while you pop off and don't forget to bring your knees up.
