Where to go next?

[Shroctagan]

I have been leveling through p99 almost exclusively duoing with my brother. We usually play in short bursts, so waiting and committing to a group for a few hours is usually not an option. We play together as a Shadow Knight and Mage, which we are aware is not the most ideal duo tandem, but that's what we played on live so we are pretty set on wanting to keep this combination. With this in mind, we have reached level 39 by working our way through UGuk, and the first part of LGuk by cautiously split pulling to break camps.

To my question, where should this duo level through their 40's? With a lack of ZEM's now, and our serious lack of crowd control, we were thinking we would be better suited to outdoor zones as opposed to dungeon crawling. So does anyone have any good leveling guides? Somewhere that gives us room to split pull, or even fear occasionally. The SK has some decent gear, including a fungi, so our downtime is usually minimal, and we would like to find a place that has plenty of mobs to keep us busy, while giving us some room to breath.

Thanks for your help!
