I also run chromatic chords of an octave with the fifth in the middle. Sore thumbs stick out. Now.. as you said..... to take things even further.... Don't forget when tuning octaves, especially through octaves 6 and 7, to check both harmonically and melodically. In other words, play the octave interval simultaneously, and then staggered. Works well with double octaves, also. The melodic octave will trick your ear into adding a bit more stretch, helping to counteract coupling effects and hyperactive attack pitch spikes from quarried hammers. A great "test" for the effect is to strike something like A5, and release. Tune A7 from memory, with at least a 2 or 3 second break. Then play the double octave harmonically. Whew! Now... pull out the ETD. Shake your head, and move on................
