Downside to wrapping is that you don’t get those nice crispy burnt-ends and bark. You have to finish on a grill after the smoke to get some of it back, but its not the same. Opinions are split on the bark, but I’m a huge fan of the crisp. Since the stall is due to evaporative cooling, you can minimize it by playing with the amount of water in the drip-pan and amount of convection in your cooker, but its still going to take longer than wrapping it.
I’m getting an Egg next season, I’ve seen it enough in action vs. other methods that it’s a no-brainer. Buy or build a good base for it and it should never break. I know someone with a Rec-Tec pellet smoker, everything comes out perfect all of the time, but its kind of like cheating, and I don’t think the flavor is as good as using/mixing hunks of wood.
