Is there a particular question you have in mind about the spacing?

I've played both and like them for different reasons:

1. For finger-style playing, I like the closer string spacing in the 18mm.
2. For slap, I have noticed (for me) a slight advantage (i.e. better feel) with the wide string spacing as an option.

The difference really, for my hands, is feel and nothing more. I could be happy with either one.

If you have grown accustomed to the 19mm, switching to an 18mm will most likely feel awkward. At least for awhile. In the end, only you can determine which feels better in your hands.

Are you considering making the switch to 18mm? If so, why?
