Not true, if you get enough revs on the ball a urethane coverstock will curve no problem (IIRC most alley balls are urethane due to higher durability than polyester). Throw two handed with no thumb with your palm under the ball and axis rotation (i.e. the axis of rotation is at an angle to the direction the ball travels) and you will get significant curve.
- nemo44x 5y agoThey’re polyester. Urethane will hook much more easily but not as much as a reactive resin (polyurethane with plasticizers) ball. Yeah you can hook it if you throw it like that but the context of the comment is rolling it reliably and accurately. Polyester balls are made to go straight. Polyurethane is even difficult compared to modern resin.
- starky 5y agoLooked it up because I was sure I heard this before. Brunswick house balls are indeed listed as being urethane [1]. I can say from experience that my polyester ball is both less durable than a house ball and curves less than a house ball when thrown two handed. There are plenty of professionals that bowl two handed like that, including the most successful bowler of the past decade. It is a completely valid and accurate method to hook the ball a lot.
