The trick to the paddle pop is to really spear it in hard like DJ was doing it projects the paddle back up nice and high and makes it easy to catch.
The gopro rear mount is very hard to get to work in surf and the only success we have had is to mount it 6 - 8 inched up above the tail otherwise when you sink the tail in a turn the camera goes under water most of the time.
The fcs plug is the only way we have found that works for the rear mount too as the sucker style mount just lets go and falls off as the water rips over the deck when you sink the tail.
my 2 cents

. I like the paddle pop trick. I have seen guys do it out in the surf when waiting for a set. Every time I try it the paddle never comes back to me and I end up falling off the board trying to grab it. 
I like that camera angle too. I think it will probably be the best all round angle for sup videos but it is difficult on surfboards as Greeny said.
