Wow, my experience with Hickory has been much better than y'alls. Drys faster than Oak, burns longer, more coals (that's good in my case) ashes are 'bout the same (? not noticeable anyways) The sparkles don't bother me being the furnace is in the basement on concrete but I could see it wouldn't be cool if I was loading the stove upstairs.
The species I was disappointed with was White Oak, still wasn't dry after CSS for 3 years, and barely had hot coals in the morning if not careful with my ash management.
