The main consideration for 1h wpf is speed. A 1h weapon with 6 PS and 120+ wpf damages fairly well. I've only 124 1h wpf and it seems to work very nicely, though I compensate with 8 PS. 124 1h wpf also seems to tip the scales slightly in terms of damage, generally giving +.5 damage whereas, oddly, 123 wpf gives a teeny bit less. Anywho, I suggest 18/18 with 124 in 1h and the rest in crossbow. I used it effectively pre-patch and was happily capable with a crossbow at short-medium range.
