I'm a fan.... have used them now for 5 yrs. I can't really think of a downfall with them.... I got the medium size so I can still run an outboard if need be. Installation is VERY important... you need to have the right angle to achieve the max performance. They work great for dogs getting in and out of the boat... and you for that matter. I also like the fact that they help w/ back splash from waves... doesn't take a very big wave to crash over a 15 inch transom on a mud boat. The pods seem to break the wave early. In performance I wanted them just for the fact that their added floatation offset the weight of my longtail.... it helped w/ the plane also.... I'm glad I got them, and I would put them on another boat again.
