Crawfish boil help

So does anyone have season amount recommendation? I have tried Frank Davis Recipe:

However the crawfish came out with very little flavor. I have tried this twice, and the last time I allowed the crawfish to soak for almost 1hr. I figured that last time I didn't let them soak long enough.

That recipe needs more celery and more garlic and probably more cayenne. Also, if you have access to liquid crab boil, I don't know why you wouldn't use one of the prepackaged mixes (I like Cajunland) instead of what is basically cayenne and salt. I usually use dry boil, liquid, and the seasoning bags (which have things like coriander and whole peppercorns.
