For myself, I would like to see the number of clubs the pros (and all golfers) carry to less than 10. I always believed that one of two things would happen in this scenario. Guys would just select their clubs and accept the limitations of the set will have to be made up with clever shot making. OR, guys will fool with the set before every round trying to get the right mix on a daily basis. In either case, I think it would promote more entertaining golf from a viewer's perspective.
Second, I would have them play on the driest, firmest ground possible. Again, I think the golf would be more entertaining to watch.
I don't know if scores would go up a lot on firm ground and with a short set, but I am not bothered about the score anyway. I want to be entertained. If players have to plod their way round, controla the ball flight, employ bobblers and wristy flops and start looking left and right of the pin as either a means to keep the shot safe or use the contours then I think they are being challenged - especially if they can't whip out a club for every situation.
