Few understand arrow paradox and how it works….they simply listen to what the “pro shop” guy tells them, and he is mostly a compound man.
I interact with a lot of archers throughout the year, and the majority are shooting arrows that are literally too stiff for their setup. Consequently, bows with B-50 Dacron need softer spines from the outset. With FF string, more energy is utilized by the arrow, with less being sent to the limbs and riser.
With old B-50 strings….which most folks are using on vintage bows like the RW, you have less energy applied to the arrow due to string vibration on the loose. There is so much more to advising about arrows than a poundage listing. Now add to that the arrow is another 1 1/2″ longer than your actual draw, and you have the dynamics for an even stiffer arrow. Archer38, do you use fastflight? Is your bow cut past center? Archery is a dynamic sport as we all know, and even though you’re pulling 47 pound, you are doing it with 2 1/2″ more power stroke than the first poster (assuming his draw is app 28″), so consequently you would immediately need a stiffer arrow.
