It takes a little while to get waza figured out and feel comfortable that you know what you are doing. It's pretty simple though if you just follow Splaves instructions for manual waza technique, which should be viewable at youtube.

That's how I learned and it works great so I can't give any special advice.
I also watched rickss69s tutorial.

I prefer the manual technique.
Good luck.
