Statics properly made are not the same performance wise as as simple selfbow.
I am for a uniform standard everywhere for the selfbow class, no bamboo, no sinew, and no recurves, that would even the playing field.
It is pretty much anything made of natural materials is OK in the class now locally, builders have come a long way in getting modern performance out of bamboo and recurving.
I am not competitive now but the guy who wins is shooting a bamboo backed working recurve osage bow with a recurve handle.
