my swap combo tier list with explanations
S - Ray Charles: hard to do, looks cool af, requires a lot of commitment on anything other than a fat tube.
B - K-fed: has a backside spin out which is a plus, and super fed is a top tier trick. Easy to do but possible to make look very cool.
C - Britney: Backswaps are cool but f2s are usually lame so the trick looks very average as a result. Super britney is much better
F - Ellen: Frontside pretzels look like shit 99% of the time and this trick is easy as hell to boot. Can only look good with full 90 degree swaps but even then it's way worse than the others.
