Thanks sa info guys, I bet your right Von! probably it's the head heavy. By the way, ang akong votric zf2 is 4u. Been using bg80 at 26lbs for many years, so probably it's not the problem.
It's great to know what racket, and specs your using! Makalingaw ug basa unsa mga preference sa laing laing players! Hope someone start a racket thread here. =)
