What is important is the southern rack: a solid Battle boots one.
Found a 48MF one on a poppable, and the only unique the rack gave lately had been...a Destroyer helm (there had been boots with low MF soon after the start of this map running, but it's a while ago now...). Well...one day it will pay off?
Is going back to the warp point a necessity? I am able to get sub 20 seconds on this map seed by using town portals instead. There's also two weapon rack shed close to both camps, though I haven't figured out how to manipulate the rack drops so I haven't bothered with those yet.
This is what I am using on my untwinked CB sorc. I TP back to town and use TK at every point possible. I make sure to TK some TP scrolls into my belt every few runs or so to stay topped off. 2-5 poppables by the waypoint that I hit at the start of each run. There's also a semi-stable paladin shield rack, which is neat. I'm sure I've had better, but this one is pretty good. And sadly it will be rolled away eventually as she progresses into leveling. Got 4 HRs in a casual day here not long ago, going to post that haul with some other goodies in the IFT shortly...
Hmmm, it would be interesting to time myself here.
