A question to people that have aoe'd at the heapFollow

Hi people, my mage hit 67 today and I went for a quick peak at The Heap before logging off, hoping to get some good aoe there. The problem was I didn't find the pulls that were good, couldn't manage to get more than 3-6 per pull.

If anyone knows the pulls that give more monsters, that you did, or have seen someone do, please try to explain them, would be lovely with a map or something if possible, otherwise just try to describe =)

Thanks in advance!
