I know this is going to sound silly, but can I just put a slim bearing in any of my throws to make them responsive? Would I also have to change the axle? ---

Depends on the yo-yo. Some you will have to change the axle and some you will not. It’s just trial and error really. ---

Replay Pro is just a bolt. You can cut it or find a different size at the hardware store. ---

You could remove the caps: [REPLAY PRO removed caps](http://yoyoexpert.com/forums/index.php/topic,84451.0.html) This would give you access to the bolt. Yes, it looks to be embedded in the plastic so it may take some surgery to remove it. ---

I’ve removed the Replay Pro bolts a few times, they’re not sealed in there too tight. There are probably cleaner ways to do it, but this is fast and effective: Remove the cap. Place the yo-yo on a flat surface with the axle facing up and bearing removed. Then just tap the axle a few times with a hammer. I’m not saying swing at it full force, but a few little taps should pop the bolt right through the thin plastic coating holding it in. As with any modifications - do this at your own risk, it can cause some vibe or even damage if you’re careless. ---

Oh ok. I thought the caps were not to be removed. I’m probably not going to mess with a good thing that much, but it’s good to know for the future. Thanks!
