Casey 1988
Shun the frumious Bandersnatch!
I read where that is not a good idea because the odds of those shots actually happening are fairly low. A better approach on tough holes imop is to simply take 3 drives off the tee using a driver, mid, putter and play them all out. That should give you enough discovery to help learn the hole.
Often these are spots I could end up on the course, the odds are not low. I am not talking the super rough parts of some courses but rather a big tree I could get next to or a bush that is at the end of the best line as an obstacle to make the course harder. These are spots that it is easy to get to on the course that do make it harder to throw next shot.
