I scored a 47 in verbal and the only LSAT material I used was the CR Bible. Most people don't know this, but the questions in it are licensed by PowerScore from past LSAT tests. BTW, I personally attribute much of my verbal score increase (from 36 to 47) to this book...
But after I finished my test I started looking over LSAT tests and found them a lot more challenging that what you'll see on the GMAT. The question structure of LSAT Logical Reasoning questions is a lot similar to that of CR, but it's "on steroids", so to speak.
Anyway, my take on it is that if you've run out of material, then why not? LSAT CR is definitely better than the CR you'll find in some prep companies' books - some of them are downright off and have nothing to do with the GMAT. The most common issue is that the answer choices are debatable:
- you either have to make too many deductions/even add assumptions to get there
- some seem better to me than their official answer
