I do prefer f/f on longbows. I owned a Pittsley Predator that I liked with D-97.
I only use 10 strands of D-97 on my longbows I had [45-50 lb range]. Recurves for me are a different story [most of the ones I've shot]. That's what is so funny.... some times one guy likes just the opposite, personal preference. I'l say one thing I've had a few of your strings Chad and they're very well made....I like the padded loops.
