I ordered all three Nylon Nylon Nylon thicknesses.
The “thick” is a little thinner than the couple other 100% nylon strings that I have tried and has a similar consistency. Relatively fluffy and yarn like.
The “regular” is the thinner nylon that I have been wanting. Smooth and snag resistent without being oversized.
The “thin” is interesting. I can see the appeal for complex mounts where thin-ness and low drag will be a benefit. But it is very light – maybe to the point that slacks and whips suffer.
I don’t think any are as bouncy as other nylon strings I have tried, but they do have noticeable give compared to Dragon/Draken/Night Moves.
