The way most folks get their airplanes "slicker 'n snot on a door knob" (as my ex partner liked to say), step up onto a slightly wet wing with smooth bottom sneakers and a slip will wreak havoc on your achilles. One visit to an orthopaedic specialist will buy a ton of ACS's wing-walk. Aerodynamically, it's a non-issue too. First, it's highly unlikely that there is any laminar flow that far back on the wing, and second, even if the airfoil could support laminar flow there, that portion of the wings are in the prop wash, which is most likely quite turbulent in that area anyway. I have an older 235 with it installed and, though I was last around the Lancair race course (first place for 235's again this year - there just aren't that many of us still flying behind an O-235), I still averaged 218 MPH, according to Lance's calculations. Give your passengers a target for their size 12 brogans - put it on.
