@@Zerthegoat2x neither could Kise, at first, he only copied GoM techniques not there physicality before perfect copy. He actually had to break his limits when in perfect copy state to somewhat replicate physical aspect. The zone is what gave him the physicality aspect without having to role play Saitama. Also Hinata did use techniques to replicate high class players in the original anime, being able to jump higher or equal to the best blockers on his team by having a running start, so I would say his height doesn’t really affect him.
