I've been using the BxM1 a lot for work lately, its more like you crawl off the HRD at a slow speed, and crawl down 5th Ave taking 15-20 mins from 143rd to 125th, and then turn off 5th at 124th, sometimes taking another 10 min to 116th, and so on. Sometimes, they use Park Ave-132nd-5th Ave which is a little faster. But I wonder if Park-131st-Lexington would be any good?
