I've tried both aerial solo methods not using a Griffin.

A Tapejara, while harder to catch because of how skittish they are, takes much less resources. You can either land the Tape or use an Archaeopteryx to switch seats midair (then throw away your poor archae). Tape method just requires landing (or an optional Archae) + tranq darts/cbow tranq arrows whereas Argie method takes grappling hooks, parachute, and tranq items.
