Hmm... I have never tried that on my SWK. My reason for doing it would be different though. It seems that the hole for the left strap is too small and it takes a great deal of tugging and pulling to get it through, to the point that I wouldnt need to buckle it after getting it through.

The bottom right strap gives me trouble as well and seems to distort the apron on all but the last notch. Of course I seem to have a rather large posterior:-)
