We haven't done this in a while, so I'm curious what the current forum audience's preferred ukulele sizes are. I included the major hybrid sizes also. If you like several, please pick the one that you enjoy playing the most.
Would you consider something like the Ohta San, (and others with a 16" scale length - Ono has one, too, right?), to be a separate category?
It really buggers me that soprano is at all a popular size, given its limitations and the overly scrunchy hand positions, but to each his own tassels.
