I'm tenor all the was. It feels right. I like the sound. Love looking at the other sizes but tenor is it! I will have tontry others but they feel small in my hands
I've only tried sopranos and concerts and sopranos seemed a little too small for me. I didn't have an issue with the fretboard, my fingers are very thin anyway, I just couldn't hold them comfrtably. I have a concert and it's perfect. Tenors should be fine too, but one of the reasons I got into learning the ukulele was the portability of it - I play the guitar too. Tenors seem a bit too large.
I've just bought a Kanilea K1 deluxe tenor. I like it, but I find myself playing my 2011 Kanilea K1 concert all the time. When I compare the two, the concert has a much fuller sound.
