Flute next step upgrade

[griffplus]

I am a violist who has completed my first year on flute and piccolo. Btw I love my emerson ironwood piccolo. I have a TJ offset cantabile II now, I like the feeling of an inline for my long viola fingers. I like the TJ sound the lower register is really powerful, spencer doesn't care for TJ at all he wants to look at older Haynes or maybe a di Zahao. how do u compare a TJ virtuoso to a di Zahao 600

My trevor James seems clunky and bulky compared to the fast action on lite response of my piccolo. I would like to find a flute that has the same responsive feel. But I must admit I really like the strong lower register of my TJ

Or any other flutes I should look at in the new/used open hole B foot/ inline
