" Firstly the Yumi is basically impossible to use on horseback due to it's rediculously large size"

That statement is so wrong on so many levels. The yumi, and Japanese archery in particular, were actually designed to be used on horseback. It's not impossible or even remotely difficult to use the yumi on a galloping horse. Before samurais became famous for being associated with the katana, they were archers first before becoming a swordsman. Try searching the internet and you'll see so many examples of samurais using yumi while galloping on a horse.
