Using the Zones... Levels...
link to the left can give you some more ideas.
Here's some of the places I go primarily for XP (group xp at the lower limits, solo at upper limits):
65-75+ DsH Farm, PoF, solo/duo Tier 2 Planes (BoT / HoH / etc.)
70+ Loping Plains (Goblins and Wereorcs and Worgs quests, there are others as well), Fortress Mechanicus (sp?)
75+ Beza/Zeka instances, Mechanical Guardian Instance, and Oceangreen Hills / Village, and Field of Scale
80+ Crystallos and various SoD zones, generally working on progression while getting some XP
There are lots more places with good XP. Necros, Pals, and Clrs seem to like HoS really well at 75+ for solo / duo XP (lots of Undead), as just an example of another spot I don't usually use for XP. I generaly only go to HoS for quests and/or progression needs ... probably due to it's constant crashing when SoF was first released. And I also add in whatever current hot zones I like for the levels for some variety. I may not do DsH Farm much any more, with over 30 levels and 1000 AAs combined on various alts there, I'm pretty sick of it :D
Hope this helps some.
EDIT: Just remembered another, that I don't usually do (due to sickness of grinding it years ago, but are still popular): 69.1 DoDh mission is great 70+, and even lower as soloing / duoing kiter class. Plenty of Dark Blue cons till around 74-75.
