I'm currently taking a billiards class as a kinesiology class for college and one of the first things the prof. said was that it was a bad habit to play with a closed bridge and that we all needed to get comfortable using an open bridge for 90% of our shots. I don't actually have a problem making an open bridge and it feels fairly natural, however, I just don't aim as well with one. I developed the habit of using a closed bridge from a young age and I'm so comfortable using it but I just can't get the same accuracy with an open bridge. I was just wondering how big a deal this is to most people. I always thought that if it isn't broken, don't fix it, but I'm no pro either.
