Sorry to say, but your new Pro Shop system is crippling and annoying, both for WGT and its members. WGT loses money; members can't buy what they want.
How about this simple idea : Every piece of equipment is available to everyone all the time, but the equipment characteristics, from mediocre to great, determine the level of difficulty; as in the position of the tees and the speed of the greens. This, in my humble opinion, would give players the best possible range of options, and WGT would pocket plenty of cash.
