A local private course had a problem. The "White" tees were pretty lengthy for some of the members (6,545 yards - 71.9/131) but the next set of tees, "Silver" was too short except for the most distance challenged players (5,767 yards - 68.1/126).
They created a "Members" set of tees using a hybrid of "White" and "Silver". The "Members" tees use the "White" tees for holes 3,5,6,8,11,12,13,14,16 and the "Silver" tees for the balance. It creates a 6,138 yard layout. The best part is they got the Golf Association of Michigan to rate this set-up (69.9/129) so one can record a proper score for handicap purposes.
I have seen a few so-called hybrid sets of tees listed on a card but never understood the system. Duh. If a course is willing to create a set grouping of holes using various tees, they can produce a very playable yardage for almost any level of ability. The beauty is they do not need to place a separate set of markers or build new tees. All the players need to do is tee off from the correct tees depending on what set-up they are playing.
It is a cool idea for courses that have a large jump in yardage from, say the "Blue" at 7,050 yards and the "White" at 6,225 yards. Using the hybrid tee system they can create a very playable set of tees at 6,500 yards.
