I have used several bags of the smaller bags of Royal Oak from Wally World and that was pretty good. Nice chunks, nothing that looked like scrap wood.
I then switched to kingsford briqs for a little while since I bought a bunch of it during the Lowes sales.
Then i bought 2 20lb bags of Royal Oak from Restaurant Depot and I was not impressed at all. It sparked like crazy, contained pieces that looked like scrap wood, had fist sized pieces of rock in it, as well as lots of dust and it burned super fast.
Now i bought a couple 20lb bags of Wicked Good Weekend Warrior. The chunks are good size, nothing that resembles scrap wood, good sized chunks, and very dense so it burns longer than Royal Oak. I have been pretty happy with how WW. PWA said something that made complete sense to me for trying Weekend Warrior. You will pay more upfront for 20lbs of Wicked Good Weekend Warrior than you will for 20lbs of Royal Oak. But you get significantly longer burn times with Wicked Good that you won't have to buy it as much as you would with Royal Oak and that is where the price will even out. I have done 4 cooks with Wicked Good Weekend Warrior and have used a total of 3 chimney's for the cooks. I still have some left over coals from my 4th cook that will fill about 1/2 chimney. If I used Royal Oak I would of had to of used a minimum 4 chimney's for them if not more.
So far I am leaning towards sticking with Weekend Warrior especially since the Ace Hardware less than 2 miles from my house keeps it in stock so I can just stop in and pick it up as opposed to having it ship to store.
