Buggyyy:
I'd play it for sure. Just please don't make it repetitive with the high winds and championship greens. Mix it up every round, so we can see some real competition.
A great idea.
From my side, please don't make it repetitive with low winds and standard/high speed greens ;-) (and blue tees for legends, making the game such that if you miss a birdie or two it's over)
Also, single play please, not unlimited, and most importantly, have credit prizes, not giftcards, as the latter are limited to few countries...
To achieve high participation, you should not limit it to a short timespan like a week (as is the case for multirounds), as people go on vacations, during which they don't play this game :) Probably the best would be a single 18 hole game per month.
