in full fare situations, i always go for f/c because the price differential is miniscule (about $30 in the case of pek-sha). however, pek-sha has been selling for less than $30 in y recently and i always jump at such fares, much to the chagrin of my knees. the way i see it, $120 at my destination is much more valuable than 2 hours of extra comfort. feel free to drop me a line if you need advise on how to spend that $120 in either city.
