If you are a natural left hander, I would attempt to switch. I am not left handed but have toyed with learning to bowl with my opposite hand. I could not urge you strong enough that if you bat, golf, write ....etc with your left hand, you should consider bowling left handed. The things you have learned over the years right handed will come into play on the left side.
The main reason I say this is because of how the brain works. It seems you are loosing alot of advantages.
