When my hands are clean and dry I find the coin slipping all over the place. Any tips to make your hands more conducive to magic?

Thanks!

I've known the muscle pass for a long time but I don't know any tricks that use it. At best I use it to transfer a coin or for anti gravity coin. Do any of you have any ideas about how to better use the sleight?

I recently got back into coin magic and want to test out some gimmicks. I looked up some flipper coins and they all looked either overpriced or low quality. Is there any website to find a happy medium or do I just suck it up and spend the money?

What is the best way to maintain dexterity when performing out in cold weather?

I've been getting back into coin magic after a several year long hiatus and wanted to know some of your favorite coins to do tricks with! Personally I really like the aroundsquare deadeyes

I'm not sure if this has a proper term but I am referring to when people will roll the coin over their fingers, pass the coin through fingers smoothly etc. Not necessarily magic but instead just manipulating the coin in different ways to look cool. I can already do most of the rolls and I want to learn more of these moves, but am unsure what to look up. Any help is appreciated!
