i have mine mounted on my spin pole about 2' infront of my front beam... lead to some interesting shots.. but kinda boring.

i have the helmet straps that come with a soft strap. works great. but you can get sea sick watching your video (depending on how much head movement you have) can also be used to wrap around the boom and face sideways.

i took my cam out on a walk and tested all the modes.. i currently use r5 all the time. makes for big files but i dont care about that much. i did NOT like the wide angles because it made everything bend and waive (felt like i was having a 60's flashback... and i am to young for that)
