FWIW, I do a Hockhurz for my N. German Pils, but I do single infusions for every other light continental lager. Last summer, when I was really getting into continental lager brewing, I did Hockhurz for everything. I haven't noticed an appreciable difference in flavor or mouthfeel since switching back to mostly single infusions.
BTW, the only reason I still do a Hockhurz for my N. German Pils is because I like doing a decoction every once in a while. Keeps me honest.
