Thanks for your reply. Hope you can get smaller retainers. I have reduced the annoying oversize retainers on my four straps by 50%. This was done by removing the topmost retainer, threading the strap as per normal except that I go through the top slot of the buckle and out the bottom slot leaving about 1,5 inches of strap. This then is between the "up" and "down" parts of the strap. So, I now have only the two retainers at the bottom, and they aren't nearly as annoying as the top retainer were. But it would still be nice to have a snug fit. Thanks for your efforts.
