It's great paper for straight lith (slow to develop, though--but aren't we all), but I love what it does in 2-bath lith; I have enjoyed fooling it in dilute Xtol (1+6, iirc), fooling it into giving up its sensitivity to fresher developer around the edges--one of the effects that you see in the example in Rudman's 2nd book--then into Ultrafine Lith 1+1+12.
