My first 2 ukes were/are Ponos, and mine are the only ukes I've ever laid hands on. I come from a viola, and later, mandola background. As soon as the first uke, a deluxe baritone in mahogany, arrived, I was shocked at how an instrument that size could weigh so little. I have some much smaller mandolas that are heavier. I loved it, and bonding was instantaneous. The second was a cedar and mahogany deluxe tenor. Even though I string all my ukes for fifths tuning, which makes them lower pitched on the bottom end than traditional tuning, I found the tenor much tenser, tighter and hard to play in the beginning. There was also the radiused fretboard, which had me constantly "missing" the notes on 1st string when I plucked tunes, due to the curvature. That one took longer to bond with, but it has such a nice sound that I determined to, and have.
I subsequently acquired a Kala spruce and ovangkol tenor and a Romero all-mahogany Tiny Tenor. All my tenors are so different from one another, and I like certain aspects about each one. it is hard to say anything about loud/quiet differences, though, because I play for myself and seldom play at full volume, so I've never thought about it. They are each very vibrant and responsive instruments. When I recall the "overbuilt" instruments of various sorts that I've tried to play over the years, the thing they had in common was they did not vibrate in my hands much if at all, and sounded nasal and "constipated", if you will.
Yes, the Pono is the heaviest of my tenors. But I do find the Pono neck shape the most comfortable to play for long periods of time. I know that's different from the norm, as I'm a woman with average sized hands, but I like something to hold onto. I like that the Kala has a satin neck, though. The Tiny Tenor is so light, but after all, it's tiny. It has a lovely sound, but not as much bass response as the others for that reason, either. And it has a difficult neck to me, as it's very shallow. Shallow necks are something I only associate with bowed string instruments which are of course held horizontally. The TT Took some getting used to, but I like it. I like all of them.
