The only problem that That I see is if you only have hickory, then that is a good problem. I have not read about of wood not to use for a probe.
I think that you will be o.k. I like how you caught the sun's rays while you were spritzing, looks cool.
On a serious note, how are the temps, WSM
's run HOT the 1st few smokes? Do you have water in the pan? What are you spritzing with?
