You could always do a "side by side" test and see for yourself what works best for YOU in YOUR circumstances.
I like the idea of mixing both, but not in layers, just mix them half and half, thoroughly together and you get the best of both worlds!
Or a third experiment!
That is, one in Happy Frog, one in Ocean Forest and one in half and half. (Happy Forest or Ocean Frog, take your pick!)
Hope this helps,... Organoman.
P.S. - I love experiments, it is the only way to find out what truly works for you and in your circumstances!
