They flip onto their back pretty flawlessly. You have to be ok with an extra pulley in the bridle on either side, but it works as advertised. Super easy to reset and relaunch compared to trying to reset on the water after releasing to a single front line.
Exactly. the pulleys don't roll when you ride powered as they are against stopper knots, so there's hardly any wear or other negatives from them.
Other than that, the Razors have really short bridles so they can't really mess up, even after being completely taco'd - upon rider error.
