Nice job, congrats on your first. Don't be afraid to try different techniques and see what works for you. My preference for butts when time is no issue is target 250 degrees, I like the bark better at that temp. I rarely foil, not a fan of what it does to the bark. When I am around 195 I start checking for tender and don't rely on temp. When a probe slides in easily you are good to go. Most important thing is to have fun with it.
