Homemade Sausage Making

I’m due to replenish my sawdust and my local butcher supply carries 40# bags. My choice would be hickory or mixed hardwood. Is there a strong feeling for one over the other? I’d be using it for sausage, Hicks, picnics, etc.

IMHO - if hardwood mix contain fruit trees sawdust - I will go for it (always).

That I don't know, but I'll ask at purchase.
