When I was younger, and was just taking up bowling, I watched the pros on tv. I could watch them, learn from them, and take what I learned to the lanes with me to improve my own game.
Nowdays it seems, at least to me, that not much of what you see the pros do in tournaments translates very well to the amatuer side of the game.
Very few amatuers will ever see those conditions, and very few houses will ever be inclined to put out shots of that type for their customers on a regular basis. Owners DO NOT want to make bowling harder, or scores lower. They know that someone else, just down the road, will welcome their customers with open arms, so they do what they have to do to survive.
You know, basketball is basketball, baseball is baseball, football is football. You can either do them well, or not. Most of the bigger sports are this way.
Golf, as far as I know, is the only other "sport" that tries to handicap their activity by making it easier for amatuers by altering the course they play on.
When I was coming up, you could watch the pros, learn from them, and apply what you learned. It just doesn't seem that way to me anymore.
I loved it, because I could aspire to be what I saw, what I admired. It just seems like two distinctly different things these days.
