thanks for the responses guys. really appreciate the detailed feedback.
i guess i won't go for the gopro and i'll see if i can get a somewhat decent handheld camera that will be able to stand up to the elements a bit. i tried getting my gf to record me with her iphone once but it doesn't really work all that well. can't see enough detail to make out whether or not i'm doing anything right.
gonna do some camera research and hopefully in 5 months i'll be posting some videos to get some analysis help. thanks again!
