We've had some pretty strong HW's here lately, and I'm struggling, especially on short final (seems like there's a vacuum on the threshold).  I was wondering if anyone has good advice or if there's any tricks of the trade someone could provide so I can stop having to go around.  I have to really fight with the PCL just to get it into flare.  Is there something I can do on my 180 set up before I perch to counter this?  Experienced pilot advice appreciated.  Thanks.   dave
