Yeah I use a pretty big variety. I don't know that there's a RIGHT or WRONG combination really.
I live right next to an apple orchard so I get free apple.
I have wild cherry on my property so I get free cherry.
I also have a good amount of oak on my property too.
I buy hickory and mesquite chunks.
I've been given pecan and mulberry by some of the Brethren.
I like to use 1 piece of oak to 2 pieces of cherry or apple usually for pork.
For poultry, I like strictly cherry or apple and maybe some mulberry.
For beef, I dig mesquite and hickory.
But it's really however the mood strikes me.
