emergency exit
The SPD normally only release sideways, or else you could really trust them to keep your feet on the bike when you are going over rough terrain or spinning to get some extra power. However I can tell you from personal experience that when you crash they will release. I have endoed with mt SPD and they came free with no delay at all. Just make sure you adjust the tension so that they don't come off too easily.
SPD are the way to go, they make spinning easy, they help get some serious height on bunny hops and generally help your technique as you have to find your way through the obstacles without putting your feet down. ;-)
