I've got some Lamkin Gripes and they work wonders.I agree with this 100%, I am using the GP CP2 wrap grips they are nice and tacky when clean but pick up everything off your hands, oil dirt etc.. I wash them every couple of weeks using dawn dish washing soup and a nylon brush my grips are 5 months old and feel like new. I love these grips but the tackiness does go away quickly if you don't keep them clean.
As for me, my grips vary from about a year old to like a week old.
