yes VG tend to be more flippy. NVD is very easy to play. I tried house shot with them and VG is harder to control. If you are sharpshooter, VG dont give you problem, else you will encounter some splits because VG flip hard.
from Heavy oil, VG handle better if you want to play INSIDE ! NVD is not for INSIDE of the lane. i tried every angle and NVD OOB dont have strong backend, but hook early.
i remind you, every ball are good, but the track path of each ball roll diffrently. You must choose which path you want to play (inside, track area, outside) and alter the coverstock if enough or not for hooking, backend, length, etc..
