Chas I do turn arounds like if the last melody note in the first 4 bars is the 5th like a G in the key of C such as. Em7, Eb MAJ7, Ab MAJ7, Gaug or(Db7#9) so on and so forth.

I tried the turnaround you suggested here and it sounds great too as do many others on Jazz turnarounds. However, they are not conducive to the, tempo of 140 unless it is a full four bar turn around and each chord is held for 4 beats. The 2 beat for holding the chord on a two bar turn around won't work on any arranger. I use a jazz guitar for comping and can get by with things like that by having it turned up louder than the Acc just leave the drums and bass louder.

Those McCoy, Hank Jones, Bill Evans, Wynton and such chord turnarounds sounds best on ballads on an arranger like maybe at 55 to 75 or 85 BPM IMO. Of course I'm a sax man, what in the hell can I know.
