Easy way to pick up experience if you have bonus exp on these mobs. I pop a regular exp booster, a killstreak booster and a MF booster for this run. I gain a 3/4 of a level in 11 mins... The video doesn't show the whole run, but even with exp tapering off at the end, we made it to level 79 in about 35-40 mins from when we started. We never let the exp booster drop off, and it paid off in the end.
