Anyone running this piece? Thinking about upgrading to this, as my old nozzle housing has a lot of wear on the inside where the o-ring is supposed to seal to prevent water blow-by. Is it a noticeable difference in thrust/top end? Also, the description states, "it has 3.5 degrees of built-in lift" Would this be the same as adding a 3.5 degree nozzle wedge? Thanks!
