Use a waterproof camera, and make sure that the tube is either shorter than the wake line, or longer and that you have a good enough rider that they won't land on the rope
Tube rope shorter seems the way to go. Pull tube from ski eye or lower pylon, not tower. A little driver / tuber skill will be required so tube can stay in table and the rider will need to be consistent and be able to control ropes on pick ups and start with a little tube wash that is a little different but it is pretty simple and fun.
if the tube comes off the wake's table and you want to get it back, have the tube rider hold onto the wake rope and then the wakeboarder can pull the tuber back onto the table. this avoids the need to do power turns to fling the tube back onto the table. keep good communication when doing this of course
unless someone has a better idea? i have only done tube shots twice in my life... too little, need to do more.
