Welcome. I have an IW 885 and my neighbor has the BGE so we share each other's meals (meats didn't sound right). I enjoy my IW885 and purchased the stainless steel box cover and plate. Makes my cooking better.
The one thing I learn is that I got so use to shutting down the grill with the app. After the app was down, I couldn't figure out how to shut off the grill. This is what happens when I get so reliance on the app.
Carolina Reapers' sauce get me sweating really quick. I am one of those that love everything hot/spicy (Mexican). But man I learn that the way hotter peppers that exist in my native land.
Welcome to the forums. I would suggest smoking a butt/shoulder. I have done both injections and non injection and they all come out great. It's ok to make mistake since it's gives you a lesson. Enjoy!
If you are cooking it at 190-200, then most likely it will take over 20 hours to cook. I did an 11.39 lb at 200 Traeger temp and took me 18 h 30 min. When I am not around like yesterday and the meat reach temp, I use keep warm function until I get home.
