Love the Looft!
If you'll: Make sure bottom is clean enough for good airflow and gate is wide open. Stack your charcoal per normal then start a little inwards of 6 oclock with the Looft, rest the barrel on the coals with forced air going towards center and down. Keep it there till you're blowing some sparks. Not the "seconds" they claim, may be up to a minute. When you see sparks back the barrel up a little for wider dispersion of heat. Keep it there until you hear the rushing of superheated air. You'll know it when it happens. Small roar. Should have flames then they'll drop out. Rotate around till about 2:00, barrel facing inward towards center, rest it until sparks - should be quicker this time - then back the barrel up and wait for that roar again. Rotate to about 10:00 and repeat. After 10:00 is going I revisit the three spots in order just to see the flames again. Then drop the lid with the top cap off, chimney wide open. Observe the smoke and in about 15 your smoke will be steady and the grill should be in the 5-600 range. Put the top cap on and adjust top and bottom air gates.
Couple variants.
For low temp, put the looft at dead center and get it going good. Listen to the roar. Close lid and do rest of stuff.
For mini I typically start 2 spots. For large I start 3 spots. For XL I'll start 4 spots.
To get there in a hurry add a spot to each.
