I guess it depends upon the flavor profile you are looking for. There are a ton of meatloaf recipes in the Traeger app. I’d probably look for one that is similar to yours and see what pellets they recommend. I really want to try a meatloaf too.
Thx guys! I did not have the Gourmet Blend but tried two of the three ingredients that I did have -- hickory and cherry. I used em in a 50/50 mix, blended together, and it was superb. Thx again for the responses.
