Here in Ontario (Canada) I'd prefer the warmth of an 8yd knife pleated but my newsome box pleat in the heat (and humidity) of summer. And yes you definately notice the weight difference. I dislike the sensation of all that weight hanging off of my butt as compared to the box pleat. Also consider Matt's strap system on the left hip. Much easier to do up as the buckle is actually on the front of the rear apron and no hole in the kilt for the strap. Consider also the cost savings of using only four yards of wool. I highly recommend a boxpleat in your collection, especially if you're keeping your kilt collection small.
