I've been a Nexcare devotee for some time!
For those who don't know, there's a difference between holding a taped stick, and holding a stick with taped fingers. No blisters or callouses at all with the Nexcare waterproof tape. And if you simply start with clean hands when applying it, it stays on. It grips great and is super flexible, like I don't have anything on my fingers. There have been many times that I realize about an hour after a show that I forgot to remove it!
I get 10-11 shows from a single roll. Last time I bought them, Amazon had a 6-pack for $21. They're now $33 and change ($5.59 ea)
and a little more at Target (sold separately for 5.99.) But it's still my least-expensive consumable, and my hands are worth it!
Here's a before & aftershow pic - I later started to wrap another piece around my ring finger to prevent the slight curling seen below (on the right.) And curiously, my right hand is taped a little differently, even though I play matched grip.
