Reddit reviews Ebonite Ultra Grip Rosin Bag

What kind of rosin bag are you using?

There are the white ones like this that emit a ton of rosin, so much that it will coat your hand:

I would only use those in very, very humid/sweaty environments and very sparingly at that, otherwise it will eventually cause sticking.

Then there are "dry bags" like these, which are more of a middle ground:

I'm not sure if these are technically 'rosin' bags, per se, but that's what I call them anyway. The rectangular "dry bag" is what I use nowadays and can use it to combat moisture all night without getting sticky. However, I still make it part of my routine to rub out my thumbhole, just in case there's buildup.

There's going to be variance between brands, so you'll just have to ask around or try a couple different versions until you find one that suits you.

If you happen to overdo it, you can sneak off to wash your hands with soap and water and start over. Just make sure to dry them thoroughly obviously. I don't like doing that when I'm bowling well, mainly for superstition, but there have been nights it helped me regain my grip.

It does get slippery when your hands are sweaty. Holoball seems to be a particular problem with this. I might want to get a bag of rosin to help, but i'm still not sure. The problem isn't so bad, my hands get way sweatier in windlands, but because you're swinging it it can slip. I've never let it go, but i have felt it slip.

Another thing that makes this worse is the controller is tapered towards the back, so when you swing it, the force actually reduces your grip on the controller. ping pong paddles and tennis rackets are flared towards the end to prevent this. Hopefully the gen 2 vive controllers take this into consideration.
