Yep... goes with the spoiler I welded to the back of my classic MG.
Seriously, why are you shooting a Hill if you're struggling to keep up with modern developments? I went through something similar and even tried a carbon lammed Hill, but it just didn't feel right. It's contrary to the nature of the beast. I decided the idea isn't to see what a Hill or American Flatbow can be made to be today, but to see what it was like to shoot one as Howard et al shot them back in the day.
That said, these bows, especially those that don't have the inserts or overlays (and Howard was adamantly against both) shouldn't be used with skinny strings. Aside from the issue of lack of stretch, i.e. shock, these bows have very narrow tips and the skinny, abrasive strings will eat into them fairly quickly. You can pad the loops, but that's a pain. Of course, you do gain about 6 fps, but the bow gets noisier. You can quiet it with silencers, but they cost you about 6 fps.
Okay, I guess I'm done... still haven't had my morning coffee so I'm feeling kind of ornery. Sorry 'bout that.... 8^)
