Yep, the dive test is my preferred method for testing CG, although I usually use a vertical dive. As I mentioned before, any time you move the CG, you should retest for thrust line.

I never suggested that thrust line adjustment was all that should be done. Just that it's a good starting place. Test, test, trim, retest, retrim, ... And after you make and adjustment, go back through all the previous tests again.
