",snapped paddles,stuck between rocks where there was no room to roll,plenty of reasons usually not mental issues,"

wavehog, you are clearly a much more advanced paddler than I am, and I appreciate your comment. However, all the examples you listed are reasons for which a roll is essentially not an option, rather than examples of failed rolls. The one exception would be failing to roll up in high wind, and this seems to be an example of what I was referring to. I think most experienced rollers understand that if the wind pushes you down on one side, you simply need to switch to the other side for an easy roll. So why doesn't that always happen? I suspect it's a mind game, not failure of technique. My point is addressed to those situations in which a roll technically is feasible, yet the paddler fails to execute one. Again, my argument is that the failure in those circumstances is far more likely to be cognitive/psychological rather than physical, and our roll training should take that into account.
