First, you don’t state what yoyo(s) you want the pads for. Not knowing what the price you’re looking at for 6 pairs of pads, I also can’t state if it’s a deal or not.
I find the standard YYF pads to be ideal for me, if the fit into the yoyo I need them for. The YYF/CBC pads fit YYJ and many other 19mm OD response pad sizes. Pads last a varying amount of time based on play, type of play and sheer amount of play. For most, pads will last a couple of months or more easily. If you’re playing 4-6 hours a day, then you’re going to be going through pads faster. I like to have a small inventory of pads on hand in case I should need something fast. I usually silicone my yoyos whenever I can.
DO NOT consider CLYW pads unless you’re using a CLYW yoyo.
