Besides a yoyo, all you need is string. And maybe a multitool, since they’re just handy.
I never use lube, I regret ever purchasing response pads, and you don’t need another bearing. The stock bearing in just about every yoyo will be perfectly adequate.
Flowable silicone, which you can buy at the 99 cent store, is in my opinion FAR better than response pads, and a fraction of the price. The only downside is you can’t throw whatever yoyo you’re using it in for 24 hours while you let it cure. I don’t see how being a beginner has any bearing on whether you should use pads or silicone. It’s an incredible simple product to use, and there are plenty of readily available guides on how to use it.
You won’t have to worry about changing response for some time though. I’d say atleast a month or two, likely longer.
