Important technique.. Thanks for posting Mike. It's a good thing to organize all the 3 note shell voicing possibilities into compatible sets and then find uses for them.

Take thirds and seconds for example:- 1,b3,3 | 1,b3,4 | 1,3,4 | 1,3,b5.

Then you could add the inversions of each of these and come up with voicings that sit well together for just about any type of chord you will normally use.
