As you know, when it's very humid, the fingers swell and if your thumb hole is tight, you have to use easy slide powder. Somebody suggested I use Lypsyl instead. Anybody else does that? Does it leave a greasy residue in the hole? I intend to try it next time I bowl but I would like some input on that so that I don't do anything that would cause a problem. I used to have the thumb hole drilled larger and use tape when needed but I got tired of adding and removing tape so now I have the thumb hole drilled tighter and I use easy slide powder.
