JJS: I like your comments generally. However, since matches are generally only 18 holes, one style of architecture will probably unfairly favor one type of player. Therefore, I think I'd strive to have balance between heroic, penal, and strategic holes, vary the lengths and balance the lefts and rights, forced carries and lay ups. Nothing wrong with an unreachable 5 on the card, as long as it's balanced with a good risk/reward challenge. My match play course would try to keep everyone in the game, and not beat a particular player with a one-dimensional design.
Hope you are well.
