Hey, whatever works for you. Yeah, it is possible to get too much smoke. If I smoke jerky (heavy) longer than an hour and a half, it can get funky tasting. The seasoning mix I use warns about that. Now I believe it.
I’ve never tried brisket. It’s on my list. Now I have some tasty venison backstrap that I need to turn into jerky.
Most recipes are good. Smoke it low and slow, and yes you can add to much smoke,spices, anything.
On steaks? fast and rare is the stuff!
Try brisket. but it needs a long low slow cook to break down connective tissue
