I think it depends on the model. True tones had several changes in the key placement, shape, etc. throughout production. It's outlined really well on saxpics.com. The later ones are pretty decent, with the half circle G# roller and such. I play on a True Tone Soprano (curved) and love it, a couple of ergonomic challenges initially but after some work and instruction from a couple of great teachers, my technique is pretty darn good! I don't even use palm key risers. I did, however, have the pearl G# removed and a roller G# (similar to what came standard on later True Tones) added.
