Yes, I use the transpose a bit. , but not every time.
While we are talking about keys, I have I had musicians say to practice intricate passages in every key.

For the most part all the jazz horn blowers with the exception of "Body And Soul," and "I cover the water front," in Db, most of the CD,s I have by these musicians, the tunes for the most part are in the keys of, Bb,C,Eb,F,G,Ab.

Most blues charts are in Bb or C sometimes Eb and F being use a bit for blues. Polka Dots F or Eb. All the things you are Ab. Days of wine and roses F. Tenderly Eb. I have not heard any famous sax musician record an up-tempo blues with the exception of Stan Getz in the key of D. Other than his tone, he just does not swing in the key of D.

I have played with guitar players where I was forced to play in E, D. It is just hard to swing on tenor sax in these keys. It is hard enough for me when I have to make a transition to a D bridge for a few bars in a Bb Blues. It is the same problem making a transition to E for the bridge in the key of C. Incidentally I am speaking of concert key for this complete explanation.
Sorry to drag on.
