I agree, flash doesn't even light up rooms like a luminous orb. it really should light up rooms though. I would say, surf waterfall strength, and unless your super mobile (IQ skill) like me and da blitz, rock smash. the HMs aren't very good in terms of power, but more used for practical reasons. example, surf and dive are used almost only to get into dungeons. strength is used only to move the position of pokemon. rock smash is used to break through walls, however if you want to break through walls, just max out your IQ, and get the super mobile ability, so that you can punch through walls by walking through them. and flash has only one reason, it's an alternative to sand attack. cut, cut, cut, I don't even know what it does, because I never have the time to get it.
if at first you don't suceed skydiving is not for you
the art of flying is to throw yourself at the ground and miss.
