Ok D_i_c_k, I agree that you should try that WT, but don't expect "magic." I suspect it'll be even harder for you to go high on than your Benge and your endurance will likely suffer. I don't know the condition of your Benge, but other options to consider are the Bach 180/37, Stomvi USA, Kanstul 1500s, Yamaha 6310Z or 8335, Schilke B6, Conn V1, Getzen, Selmer, etc., etc.
If you play a trumpet and it makes things easier for you, buy it! Doesn't matter if it's a WT or a Kanstul "student" horn. Of course, you should compare several, just in case ANY horn is "better" than you Benge.
Happy hunting,
Dave
