I have some of the same thoughts as Doc. I primarily play responsive, all but a handful of my yoyos are in some state of responsiveness. I’d highly suggest just lubing the stock bearing, or if you have a bearing that is already deshielded use that one.
Again, JHB linked it: Page Not Found | Super Lube This is basically what I use, 3-4 drops or more if you’d like.
You said that there was a delay in the response when you lubed your bearings in the past, that’s not a bad thing. That can actually help you learn unresponsive play. Having a little responsiveness can help in learning to bind too.
While I do like half spec’s in some yoyos, most just do not perform right with them. And if you want to get into unresponsive yoyo, I’d really suggest not going that route, a spec and a full bearing play completely different from each other.
