Re:coil, RR, Confident Coils, and Angell - suggestions for use?

Ok, so I recently bought the above products, and I am looking for suggestions on how I can combine them to make them work! I realize I may not use all at the same time, but what are some ideas for how to make the most out of my new splurges?! Oh, and I have what I think is 3a, medium thickness, just above shoulder length hair. :)

Thanks for any tips!
