Talk to your husband's friend, or someone else at the bowling center who bowls pretty well and also knows your husband. You don't want to make the mistake of getting him something that, while brand new and his, as opposed to used and borrowed, is actually less effective than what he's using now.
Case in point. I bowl with a mildly retarded guy on Sunday night. Every two years, he gets a new ball for his birthday. When I first met him, he was using a mild reactive ball, something like a Scout, and he carried a 150 average.
Last year, I guess someone tried to save a few bucks, and bought him a plastic Target Zone. Now, his average is 139, he can't carry the 5 pin to save his life, and he's miserable. So I'm having the pro shop plug my Flipside Wild, and drill it to fit him. I'll bet his average will be back to 150 in no time.
