we've done those types of governors in the pit a few times... we now refuse to do them because they are crap.... had several pass a state test one year only to not work properly and fail the next. they are hit and miss which is why we now use only hollister whitney. truth be told i've done so many roped hydros that i'm comfortable with them, they definitely are a little more work than other hydros obviously but they aren't too bad once you get used to doing a bunch of them
