I'll be getting my BW on Monday and will be rolling a few games with it to get the feel of the ball before summer league starts. Right now I throw a conventional Ebonite ball and average around 170 so I hope this ball improves that average. The lanes I bowl are med.-heavy oil. The guy that runs the pro shop there says this ball is ideal for those lane conditions, so, we'll find out soon. I may take my Ebonite with me for spares until I get used to the BW because I've never rolled a fingertip ball before and it may take some time. I'll let you know what happens.
