I may be in the minority here, but I prefer tighter spacing. Unfortunetly, there isn't a whole lot of 34" scale six string MTD's out there with 16.5mm string spacing. That would be my ultimate comfort zone. But, like always, I've adapted to what is available, and I am getting more comfortable on my 35" scale bass with 18mm spacing. It is taking a long time to get as fast and precise as I am on a tighter spacing, but it is coming along.
