Highly disappointed with my GMAT Verbal score

Hi Folks,
I just took the GMAT two days back and performed horribly in the Verbal section. I scored 660 (Q50, V30). I did not feel very nervous during the exam and particularly found the Quant section to be a piece of cake, but verbal seemed to have much longer passages than I have seen (with 2 long RC passages). Here is a background on my prep:
I spent approx. 2 months preparing for the GMAT and used the following resources:
Quant
- MGMAT Guides
- Target Test prep
- OG Quant
Verbal
- MGMAT Guides for RC, SC and CR
- OG Verbal
- About 40 of the Artistotle RC Guide passages
- Powerscore Bible for CR
I took all six GMAT Prep Practice tests and scored between 680, 680, 730, 680 and 710 with verbal scores of 35-41 in each and Quant scores of 46-51. My target score is at least 700, and am planning to retake the test in 15 days but this time honing in on my Verbal skills. My ESR showed accuracies of 35% RC, 70% SC and 70% CR. What resources would you recommend I use to practice RC's and CR questions for my retake? (OG or GMAT Club RC's). Also, what are good sources to practice SC and CR.

Thanks for your help!
