I said it differently above, but using two good (but different) tools for the same task is acceptable, and there is no argument anywhere to be found. Like in many other pursuits, the experts get where they are by employing many different processes; even when using one is fine. The theoretical approach can appear wrong when it isn't, it's utility is elegant when used to build a foundation.
In problem solving groups, I have heard (and used) the expression, "Let's look at this a different way", or, "Let's unwind this tangle, and start over with a different method."
I like Newton for air handling that is "complex", because it is simple in that domain.
Bernoulli is a complex way of understanding something straightforward imo.
One can get bogged down in the math, and the simple equations are my friend.
The "all-flying tail" can be a flat slab, the nuance is on the top, the basic work is on the bottom.
