I've seen it mentioned several times in passing that using pin nocks has the effect of increasing an arrow's (dynamic) spine. Is there any rule of thumb for just how much stiffer the arrow will become, i.e. will a pin nock/bushing make a .600 act like a .500, or . . . is it a smaller degree of difference related to fine tuning and dialing in FOC?
