Completely agree. 1 bag of Royal Oak Lump burns for 15 hrs in my UDS @ 230* or 8 hours @ 300* with a third left over. No real packing needed, just dump it in shake it a bit to settle and light it. The only temp swings are usually self induced by making too many adjustments instead of letting it do what it does.
