I do not have hinges, and there are times when my jib hangs up when i tack. But I have found that having a more smooth tack or jibe helps alot. I used to have very sloppy tacks and that caused the jib to hang up very often. I would recommend trying to improve your tacking technique, Im sure there has been a post at some point which can help you with this.
Also, Im not sure if they are class legal. I know that Hobie's "light and limber" jib battens are not, but are the hinges legal?
