Yeah I do. I usually over-fill the basket (UDS being so fuel efficient and airtight that it'll easily extinguish leftover fuel - always better to have too much in there) and dump half to 2/3 of a lit chimney straight on top (no need to make a hole) if I'm aiming for 250ish and a full chimney if I want to get to 300-350. I've often wondered why people bother with briquettes when lump does such a good job. And from shops it's usually around £1/Kg
In terms of wood usage for that kinda fire I just chuck a few lumps around the edge of the basket and one near to the centre so it catches straight away. I often find that after 6 hours or so I might get a bit of a temp drop, so it's just a case of switching up the vents to even out the burn.
