I speed pull and chain pull. On experts I don't feel comfortable speed pulling so instead I chain pull. My number one focus is to maintain threat. As a VIT PLD (I learned my lesson just recently) I can't handle the threat of larger pulls when you have cracked out DPS. Or maybe it is my own paranoia but regardless there is no wasted moment in the run. Once the last mob is at 10-20% I am grabbing the next pull. I want to be as fast as possible but depending on the group make up it is much faster to single target than AoE and vice versa.
