Sounds to me like you're fine on string procedures. That one may just not have the upper loop quite big enough. Some recurves have really wide limbs.
Personally, I prefer Flemish strings. Especially once I learned how to make my own. Making a Flemish string is a black art to many archers. You may make great bows, and really beautiful arrows, but make a nice Flemish string and you'll find some folks bowing to you
LBR, the moderator here, makes and sells great Flemish strings. I don't think he uses the forum to push his sales so you may have to contact him to ask directly.
