I had a chance recently to try 2 alto 67's and 2 tenor 66's and found their sound to be very good and what I was looking for. Nice darker core, sort of the opposite of my yani's. But the build quality was poor. These horns felt like student knock offs compared to what I'm used to. With further inspection I noticed the palm key cups were in general too small as the rolled tone-holes were right at the very edge of the pad, others needed realignment, the octave mechanism didn't feel solid and in general the horns didn't inspire me to want to play them. Honestly, the Barone horns I tried had a much better feel so I guess all Tiawanes horns are not the same.
