When I had my mainsail made I had the sail maker include the dogbones (strops) in both reef cringles and I had him add a web nylon handle above the cringles so that you can pull the sail and control its movement while setting the dogbone. I have considered making my dogbones longer by removing the strop from the rings and just using amsteel to tie the rings on either side of the cringle.
I already have a 4:1 cunningham so an extension of the idea above would be to have the length of amsteel long enough to hook the horn opposite of the cunningham then set the cunningham hook in the eye that is sticking through the cringle. Now when you pull the cunningham you get a 8:1 advantage as well as a lot of flexibility for tack height. One concern is that this orientation may not hold the tack in position fore and aft relative to the horns. So if you absolutely want strops you'll have to get your sail maker to add them.
