What works best--a Sling, The Mule, or a Kayak Cart?

As I stated in my product review, the Mule is a good product.....HOWEVER if you have a SUP with an especially wide and squat tail, make sure that you have Mule send you an axle that is 4" to 5" longer than the one they normally include in their standard "big board" package.  I have a Jimmy Lewis 11' SUP that does have a very wide tail, and the first time I used the Mule, it damaged my board because the wheels did not clear my back rails.  They rubbed off about 1/4" of the board shell on each of the back rails where the wheels rubbed on the board.   The people at Mule were very responsive and immediately sent me a longer axle and now the Mule works perfectly for my Jimmy Lewis.
