You'll find lots of threads about Kingussie pleating in the general kilt talk and the DIY forums here. You are right about this being an "old" style, but I'm not sure I'd reserve it for the "adventurous"...unless made with bright purple urban camoflage.

Several members here swear by Kingussie pleats for hiking and outdoor use since the pleats facing rearward are less prone to catching on passing shrubs and briars. Makes sense, but I've not made one for myself yet so I can't offer first-hand testimony.
