Good thinking although, you in my opinion, still have some faults
Everyone that can do PATW can do alatw, but can everyone that can do alatw do patw? Therefore, alatw eliminated from the list.
Same with ahmatw and skora atw (if you can do skora atw you can do ahmatw, but if you can do ahmatw it doesnt mean you can do skora atw)
kamatw and beck atw can also be taken away because for obvious reasons there about 100 people who can do those tricks which makes them deffinately not the hardest
note This is only my opinion

you can do anything that you want. I'm just giving my point of view
