I did one party fresh, then and imported one, than another new start.The last was my favorite, I think because I new the "ins and outs" a bit, and was playing a path I discovered I had missed in the previous game.
It tookk some fun out of it, not being able to share (and commiserate about not knowing the answers), but was a treat ... reminiscent of Wiz 7 days, when there was no board 
Incedentally, that last party had no psionic or alchemist, but 3 fighter, samurai, gadgeteer and a valkyrie.
