Just wondering what difference, if any, there is in these two balls.  I've been using an old Zone ball (and it's not a T Zone, or at least all it says on the ball is Zone) for spares for the past several years or so but one of my teammates gave me a brand new Maxim he won at tournament a while back.  He's telling me I should go ahead and get the Maxim drilled because we are moving to a different house this fall for league, which has wood lanes versus the synthetic lanes where we were bowling, and he seems to think the Maxim would be a better spare ball for the wood lanes. And I can say that with the Zone, when I (try) to pick a 10 pin on the wood lanes, I'm finding the ball has a little movement on it and it will veer/hook off at the last second, leaving the pin.     

Any thoughts??
Thanks!!

Not really. The only noticeable difference might come from the different coverstock finishing methods between Brunswick and Ebonite. That can be changed by the end user though.

Which is probably a good idea anyways. Especially if it's an older spare ball. The surfaces on plastic need to be refreshed (killed) every now and again if you want to keep it going straight.

Plastic is plastic especially if both have pancake cores.  Might as well wait to drill the 2nd ball until you need it.  Some people on here seem to shred plastic balls every few years (keeping my opinion about inserts to myself) so you might need it someday.  At least with plastic your risk of cracking in storage is pretty low (especially with pancake core).  Stored mine in a garage in Sonora heat for 5+ years (long layoff) and it still rolls like a champ.
