to jerry, when you sping them in water is the spine up or down? am confused on term crown. do I place my cock feather on the upside or down side. I don't have any bearings to test the arrow with unfortunately.

to jeff b. thanks for the info. but, when I goto my local archery shop all the arrows are in a big bin and not grouped from by the dozen. is this how they are at you shop? how then do I not mix and match them per say? are they sold to the retail shops from the manufacturer by the dozen? whooshh lots more questions as I learn about this subject. its kinda like building a fly rod and having to learn about the spine except arrows are a lot smaller and you cant flex the sections like you a fly rod.
