Looking for "Style Combos" to lab while I'm in schooling

I just started my third year of Uni so I've decided to take a break from online Fighting games, especially T8 but I wanted to know what sick loops your characters have for me to practice.

Things that might not be optimal (Bryan QCF+3 loops) or things that just take a lot of practice (Kazuya DF+2 > Electric launch) would be awesome to hear about!

If there are videos showing it off just so I can see what they look like or if I should learn them on stick/Lever less for an extra challenge would be awesome to know about!
