I love my sabre but it can open too fast if you don't roll the nose enough. I sometimes roll the heck out of it to ensure an average opening. If you don't roll it at all, it will pop out in a hard opening and give you whip lash! I like to re-pack mine before jumping it after I haven't used it in a week. I noticed that if I pack it at the end of a weekend, and then jump it five days later with out a re-pack, it will give a hard opening.
