Never played kitty nylon, but I make nylon string so I kind of know. Nylon is rough, think toxic dragon filled with glass. Well, maybe not. However, it is very unforgiving and will string burn you in an instant if you play fast. It’s really hard to describe how the nylon roughness feels. I don’t mind it, because I play slow. It’s a unique roughness though. You’ll just have to play nylon and decide for yourself, I can’t describe how nylon feels.
The appeal to nylon is that it’s heavy. This means that you can make very whippy string, while keeping it thin. Nylon is also kind of slippery and very slick, so people who like a little bit of slip in their response will like nylon. Nylon also holds it tension relatively well. It’s really all preference that decides if you’ll like nylon.
Do you play slow enough to avoid string burn?
Do you like whips and slacks?
Do you play fast without a glove?
Don’t pick nylon.
