I love that Tony grabs everything he throws. I guess that must be the west coast style shining through. Looking forward to seeing a video where we can see his grabbed crow 5 and 7's and 9's that everyone tells me about but I don't get to see.
The thing on the tower is an attachment for the line. It takes it up a bit higher than the mount point on the boat, however I don't believe Tony was using it in the video. That grabbed backroll was to legit
