Where do you stand on sales training?

You have decided that you are willing to investigate sales training - which method did you find more effective? Some friends are saying that one-on-one sales coaching is very beneficial. Then another prefers a sales process to keep them on track. I am assuming it has a lot to do with your personal focus. I am going to try sales coaching. I think I just need some tweeking to my approach. I'm curious about what the rest of the world is doing?
