I bowl twice a week, average between 215/220. Have several 300 games. 1 800 series. My golf game is 10/11 handicap.
Bowling has become much easier in the last 10 years. Between the new equipment (balls) and how the lane owners now are oiling their lanes, 150 avg bowler 10 years ago is now a 180 avg bowler, 180 to 200. You just need to be consistant in hitting your marks, with the same tempo.
Bowling lanes are flat....not like rolling greens. I've never had a problem with weather conditions, (wind) bowling indoors. NO HAZARDS, same distance. The ball is in my hand, I have total control of the ball, not hitting it with a stick.
I also practice alot at the range for golf, never practiced for bowling.

Bowling is something I do, to get thru winter.
