Hey Pin,
I've been explaining this to my students for years, good athletes NATURALLY adjust. If you bowled on a very dry condition all the time, your natural game would become either very high speed or you'd learn to spin the ball to delay it. The same goes for the opposite, if it was heavy oil, you'd probably have a very natural slow speed and strong turn because that's the way you would tend to score higher. These things to me are very natural to those who have touch or feel, there's nothing wrong with it. Equipment has changed this a lot now because you can go out and buy hook vs back when I was young, you didn't have that luxury.
