'crafty, firstly I have to add to the long list of thanks for taking the time to post up these informative threads!!!
Secondly - you're using secondary feathers but will tail feathers work just as well? I think I remember an article in one of last let's issues about it.
If/when using tail feathers, is there a preferable side to use as the fletching? I mean with regard to "left wing - right wing" feathers, cos tails are "in between".
