pin up drilling usually save the most energy until later down the lane.. you should get more of an angular(hook)reaction with the pin up.. as for will it hook more it depends on where you want the ball to hook.. bowlers view hook in 2 different places, early hook or angular hook.. pins up hook later(for example down lane) and pins down hook earlier(for example closer to your feet).. then you have your mid lane(hook/read), but thats another story..lol..
