If it is not raining when I leave the house, the Sling is going with me. You will miss a lot of good riding if you go by the weather forecast. When I say cut the nannies off in the wet do it . It just might keep you from spinning out. All three wheels are supposed to be running at the same speed, if they are not then the nannies do it for you. "IMHO" A way of thinking about this is when the nanny is applied to one wheel in the wet it spins you out. In standing water this does not apply, you are going for a ride anyway.
