V40 Retake strategy

Hello, I recently took my first GMAT attempt and scored 620 Q35( ) V40. Nearly ALL of my prep time was focused on Quant, and I was consistantly scoring Q40-45 in MGMAT and GMATPrep tests; however, I lost track of time on the actual GMAT and got down to 11 minutes with 10 questions remaining . So, if I would have scored my average quant score with the 40 verbal I would be in the high 600s. I hope to join the 700 club, so my question is: should I spend more time prepping for Verbal this time in hopes of raising that 40 to a 42 or 43 on the retake? I ask because I barely did any verbal prep for my first attempt and just went off of instinct. I plan to continue to drill quant in hopes of 45 or higher, but I'm not sure if it will be worth the time to drill verbal.
