Hi Ron, welcome to the site.

First I would have to recommend you get a fingertip drilled ball that fits your hand properly and some lessons, and your game will improve very quickly.

As far as muscling versus a free gravity fed swing, the free gravity fed swing will improve your game faster and cause less bad habits in the long run, but in order to do that you need a ball that fits your hand properly first. If you have to squeeze the ball to hang onto it then you have little choice but to muscle it, so start at the Pro Shop and go from there, if you need help, let me know what town you live in and I will try to help find one for you.

Hi Ron, welcome. If you can post a video, the many watchful eyes here may be able to help. Good bowling.

I'd also like to welcome you to the site Ron. I can't add anything as the previous two posters covered the important parts.
