I have Old Man's War
in the queue as well, just having fun working through unread things from the old masters first.
ty for the recommendations, the only Pohl I've read are the Heechee books IIRC... and I need to read more Poul Anderson in general, whatever I've read of his is lost in the misty depths of time.
BTW-love your sig. Here it goes now, the circular motion-Rub it!
