I use floats on one of my planes, to fly off the SNOW. Skis are smaller, and tend to drop in to foot prints left by others who walk across the middle of the runway to retrive planes, instead of walking across the end. I prefer the GeeBee brand floats there is no assembly to the float itself, therefore no leaks if using on water. They come in a couple of sizes, and Tower has them,28" $33.99 & 33" $39.99.
