Anyone use the "Low Drag" Buoy ??

[Gooseman]

Came across one of these the other day surfing the net. Looks similar to the round balls most everyone uses to pull their anchor, except it's more of a cylinder shape.
Claims to only create 20% of the drag at retrieval speeds of 3 to 6 knots. Also listed as the Alaska crab fisheries buoy of choice.

Anyone try one of these for pulling up an anchor? Reason I ask, they are about 1/2 the price of a round buoy, and look a lot stronger.

It's the drag from the water that helps pull the anchor. These wouldn't work as well as the round ones.
