Bracha on Tallis

The Yefe Nof (a Posek from the time of the R'mo) says the Brocho is Betzitzis.
But R' Zalman Henne brings that the minhag was to say Batziztis, and also the Divrei Kehillos pg 23 (note 13) brings that this was the nusach (although he says one should say Betzitzis), and that is the Nusach in Avodas Yisroel and the Rodelheim. The Yavetz also says one should say Batzitzis.
