A long path
First I used the cone chalk like I saw most other people use, generously! Baby powder if that was all they had but it has oil in it that gums things up worse when mixed with sweat or dirt from the tables.
Then when I started toting my own cue, nothing. I cleaned and burnished the shaft at least once a week and it was slicker than slick.
When I came back to the pool halls many years later I alternated between nothing and the tiniest amounts of powder, mostly on the shaft of the cue. However playing down in the humidity of New Orleans and not being as young as I once was, I sweat a lot. Between that and the dirt and smoke residue on the tables the shaft of my cue often becomes a gummy mess. I wash my hands a lot and use the damp paper towel trick on the cue. That helps a bunch but I was still fighting a sticky shaft.
Finally I tried a glove after resisting for several years. It solved the stickiness problem, my cue shaft might get dirty but it didn't get gummy. The glove fit poorly and cut into my hand and my fingertips not having direct contact with the table left me unhappy. Have to admit, there are places I shoot pool that a glove will cause people to question your manhood too.
Enter the fingerslides: They don't look like a glove and they do the same job while leaving the fingertips exposed. A little tricky getting the perfect fit if a standard size doesn't work for you but Nancy will work with you to custom make anything you need. Once you have the fit you need she records it and you can get duplicates any time you want some. The finger slides are reported to last far longer than gloves but I don't know, I haven't worn out the first set yet.
Under ideal conditions I favor a clean smooth cue and clean dry hands. When conditions aren't ideal so far the finger slides have been the best solution for me.
