Yes, they come responsive, and if you want them unresponsive, you will need a c sized bearing for each. Replacing the response is optional, the yoyo will work fine unresponsive, but it turns the string black. so i would suggest new pads, because flowable silicone seems to fall out kind of easily.
To make a YYJ Classic unresponsive all you should need is a clean (preferably concaved, grooved, or center track) bearing. If you want to go a step farther; remove the silicone stickers and replace them with ‘flowable silicone’ (preferably MFD ‘Monkey Snot’ as it is quite easy to do. Try to get the flowable to be slightly recessed (rather than ‘flush’ like the stickers were). To do this fill the grooves w/ the silicone and use a card scrape the excess at an angle. You’ll know u did it right if it looks like the silicone has a groove or concave. Let dry for 12 hrs min.
I decided to get MF silicone instead. It will make my yo-yo’s look cool. I also got a pair of Crucial bearings. While I was at it I got a 100 pack of Kitty String. Yay
I prefer pads in my classic… I tried YYJ pads first and they did not bind all that good… VERY loose… I took them out and put in a set of YYF natural pads… NOW this thing plays great!!!
The Classic set up with the right pads and a C sized bearing is a VERY VERY VERY good yoyo!!! And for the price it is a steal!!!
Actually, I am not sure. They are pretty light, and they will not spin as long as metals, which is helpful for beginning 3A players. But for the price, theyre great.
