Back before I broke my arm and fractured my elbow, I had given this some thought. I have, since I became reasonably proficient, always been a slowish, rev dominant bowler. I have been able to change me release some, adding a bit of tilt (yes, tilt), which allowed me to get a bit more length and a smoother reaction, but I still had trouble with the balls just being too strong for me most of the time. When the oil seemed good to me, 80%-90% of the other guys were complaining that their balls "wouldn't hook", so I knew I needed to learn how to bowl on "their" condition, but I was never fully able to do so, so I just did the best I could with what I had and was afraid to "screw up" an expensive ball by drilling it conventional.

 

 Then, while I'm out of action and healing up, I come across this guy, who claims to be using conventional grip stuff, and also claims to have 34 300's and 17 800's while using it. I know it is a cake shot, but give it a look and see what you think. http://www.youtube.com/watch?v=MRD0ocDtv3w .

 

 Now I'm really thinking about drilling one up conventional for when I can bowl again. My grip strength isn't going to be back to normal for a while, and I just need to get my elbow used to handling the weight in a swinging motion, but I also want to score as well as possible. Do you guys think that this might be something I could expect much out of or not?

juggernaut......Back in the "early" days we used to go forward(towards the fingers 1/2") then start putting some reverse in the thumbhole till you could clear it.

 

If you have access to "help" we also used to "teardrop the fingers and thumb".     This is a stretched conventional with the inside bevel on the thumb and fingers carved(beveled) out(teardropped) til the hand lay flat on the ball.
