Thanks for the feedback all. I suppose they were on the smaller side and somewhere between out of the fridge and room temp, also being a mild So Cal climate, I'm just going to assume they're a faster cook to temp. which I'm ok with.
Good call on the ambient probe, I'm going to test that out.
At the end of the day, they were great! We actually had a last minute birthday party invite, so I brought them wrapped and just finished them on the grill.
Next time I'm going to cut back on the smoke (5 oz was too much), and will shorten the rest period (unintentionally long this time).
