In a sway condition, if you have lots of room ahead- - - - - -
If a frog had wings, he wouldn't bump his bottom when he jumps. I prefer to be able to deal with a dire emergency RIGHT NOW, not under some mythical ideal set of circumstances. I've had to recover far too many wrecks that resulted from someone who lost control of a vehicle to trust my safety or the people who share the road with me to luck. The only thing I've got with surge brakes right now is a 2-wheel tow dolly, and I'm seriously considering converting it to electric brakes to match the rest of the trailers I own.
