my idea was to cater to the "longest time carry" crowd while still being possible to sell the same clip for general l&c fans at clips4sale. the good thing about clips4sale is that each clip being sold separately instead of a monthly membership allows for a range of different ideas and experimentations. you said you can go up to 245lb person for a lift. a clip of one type of carry at longest time would most likely be under 10mins with someone that big. so it will still sell (not very boring) to general lift and carry crowd.
there are tons of variations (f/f or f/m) (specific lift specialized clip) (bigger liftee or smaller liftee) and so on. i think you can cover all of them on clips4sale and still make money
