I usually do pairs first, but not ignoring centers. I try to influence them as much as I can while pair solving, which can up the movecount, but speed me up later in the solve. Then I do CLL/OCLL depending on how much I dislike the case. Then fix centers (usually just one slice move, unless I completely ignored centers during pairs). Then solve three edges, and orient edges while placing the last edge. Then it's EPLL/PLL.
For my PBs, it's hard to say. I was faster with it a while back, but I've erased my times database since then. So off the top of my head, my current PBs are:
sniggle: 10.xx
NL sniggle: 13.xx
Avg5: 15.xx
Avg12: 17.xx
