When I was growing I would usually make edibles out of the trim and smoke the bud as you suggested.
However, now that I can get killer bud for cheap I've started using whole buds for the procedure and here is what I've found:
It taste better and is usually slightly stronger as well. It's very comparable to the difference in a BHO run with trim versus a BHO run with bud. The bud run is slightly stronger and usually taste much better than the trim run.
Now with wax, for me taste is nice but not the biggest problem. With edibles, taste IS the biggest problem. Trim usually taste like eating grass cuttings unless you make extra steps to filter out the nasty tasting stuff.
It's easy to make strong edibles, not so much good tasting ones. Good luck!
