What you refer to as the "old Masters tees" are basically the same as the members tees. These will never change. The other set "the tournament tees", are in a constant state of flux, expansion, movement and change. Number 11's tee was in fact moved to the right, to make the hole play like more of a dogleg. Its a 290 yard carry to the top of the hill, but cresting the hill at dusk and seeing 11 green, 12 hole and 13 tee is a true breathtaker.
