I still don't like that bowling has been reduced to this, though. You don't see golfers digging troughs in the greens to make their path to the hole easier. Bowlers mangle up a tough pattern so that it plays as easy as a league shot.
Bowling hasn't been "reduced" to this. That strategy is as old as lane oil itself. It is just a bigger phenomenon now that these "nuclear powered" bowling balls are all the rage. Back in the rubber/urethane days, "carving a line" wasn't as big a deal
cause most of the time, there was only one (maybe two) lines to play on the lane. Now, a person can play deep inside or up the board (or a combination of both on two different lanes). The game has so many variables now (oil ratio, pattern, ball, lane surface, etc) that creating a line is about the only way to be competative. And it's not like there are only a few folks doing this... just about every player on tour (National and Regional) does this or has done this. It's just a facet of the game.
As for golfers not doing this... that's because there is nothing that he/she can do repetitively enough to change an environmental variable to favor his/her game. That's inherent in that game. Carving a line is inherent in ours.
Like I said earlier... some folks find it unfair, others don't. But if you go to a tournament (especially a scratch event), you should prepare for it cause everytime I've seen blatent examples of carving it has always been at these types of competitions (house scratch, high roller, regionals, national events, etc). It seems that when a bowler bowls for money, he/she will do what it takes to win.
I like that.
