All companies have to start somewhere, but the bowling industry is pretty much flooded with products already.  Unless you can find a way to make a quality high end reactive ball and sell it for under $70, it will be extremely difficult to get people to try your product.  If you were an engineer of sorts I could see this being a little easier, but you would have to hire someone when it comes to core designs.  If you have someone else pour your stuff, that will be costly with minimum orders that are pretty high.  I remember Mo saying something about minimum orders but cant remember the number.

But if you have an endless supply of money and you don't mind throwing away a few million just to get off the ground, go for it.  It sure would be fun!
