I'm not sure a spine chart for
longbow would really work. recurves are more consistent with how they work, and with the arrow being central to the bow it can be calculated more easily.
With longbows the bow is a factor. Ignoring the material of the bow spine depends not only on the poundage and draw length, but also the speed of the bow and it's width. For example an Aidy Hayes bow is thinner than a Bickerstaff bow so an Aidy bow would been a stiffer arrow as it doesn't have to curve around the bow as much.
Simon I have a similar thing, I have a 65lb bow and a 50lb bow but the arrows fly just as well out of each, due to the different characteristics of the bows.
