I love Whipples! At first when I used mine for some reason it caused a bad vibe but after I cleaned it it played amazing.
I like no shields so it was good. Just makes it easier clean some of my bearings have 1 shield though because I’ve noticed C clips are a pain so I don’t waste my time. I like how CTs come with shields but no C clip so the shields come out easy.
The bearing shield is the part of the bearing that isn’t visible with the yoyo together, but the part that faces up if you were to take the yoyo apart and put the yoyo half (that has the bearing) down. The shield isn’t totally flat. Hope that made sense, LOL.
I used to like mine shielded partly because I liked the idea that they were closed off from any dirt, partly because I felt that it helped keep lube in. Now however once they are unshielded they are unshielded. I always keep the shield and c clips though. Ironically I used to worry when I lost a c clip or shield, and now I have extra that I don’t use.
