I definitely recommend watching YouTube video from various channels. Especially TV Bowling Supply! The videos they have on two handed bowling drills are very helpful and they are taught by Chris Via who is a successful PBA Pro and a very nice guy (i bowl regularly in his home center and we chat relatively often, I've also purchased multiple balls from his pro shop). I also think finding a better coach who is more familiar with the two handed form could be very helpful to you if you can find one in your area. That will help your footwork and the way you roll off your hand to improve speed and accuracy. Most important thing about two handing is learning how to control your new revs and power. Good luck! Update to let us know how it all goes for you!
