Going back to original problem....

How the kilt hangs in front and back, depends on how pleats/apron split is done (IMHO). Reading literature and working on my own diy kilt, I believe simple 50/50 split is not always good. If you have more "flesh" on back, more hip measurments should go into pleats and if you have more in belly you should accommodate there. This way bottom adge of kilt will hang properly and assuming seting would be no (or less) issue.

But, this is only my thinking. I'm not kilt master (yet)
