I love to watch a well thrown roller. I agree with Mike C that they are under-used, but that may be because the courses that I typically play aren't roller friendly because of tree roots, branches, or just about anything else that can be in the fairways. I will almost always air a disc out if I have any chance to, but there are times when a roller is the best option.
The last time I threw a roller off the tee, my disc turned over perfectly for the roll I wanted, a sharp turn to the right, but it hit a tree root shortly after starting to roll and it popped way up in the air and came down and stayed right on that tree root :wall:
