I often move between a Marleaux Consat which has 19mm spacing to a Stringray 5 at 17.5mm
The difference is very obvious, but I really like both.
In the past I've owned a Status with 16.5mm spacing and it was far too narrow for me - even for non-slap work. It's only 1mm tighter than my Stringray5, but it was so very different to play.
