I have used the V drive version and the center pylon version.....I sent the V drive version back. The way it is angled and such it seemed like there was a ton of force/leverage on the side of the boat. Also, it made it hard to open the rear doors while attached.
That being said, the center pylon Barefoot boom is one of the best investments I think you can make on a boat that you often have noobs out on. I started my kids out on it and it was a very smooth and quick transition to the back of the boat.
