I have a set of these mud sliggers at home. I ran them on my Max a few times and here is what i found. They help with water speed a tiny bit but you lose some of the control you have with out them. They also require to keep the throtle just open-or the tires moving slowly for the paddle effect to work. Speed up just a little bit and they stop working or push your AATV to the side. I really didn't test them in the mud because I seem to have all the traction I can handle with my current tires. The mud sliggers are easy to put on and take off but they quite expensive and overall not worth the time and effort. I only tried one set-it is possible that the effect could be alot better with six of them but that is a lot of money for an experiment!
