My wife is short. Her 2009 TW is too tall for her to reach the ground comfortably (I too am short but at 5"8" I easily flat-foot my 2008 TW). I would like to reduce the seat height on her 2009 such that she can place both feet firmly on the ground while on a level surface. She needs at least 2 inches of height reduction. One thought that I've had is to simply remove foam from the seat. I am looking for any thoughts or direction on this issue. Thank you, Brad
