I have a number of longbows,,reflex deflex,,but my fav is a 60lb Jerry Hill Wildcat delux,,,ya hand shock soo bad you get headaches after 10 shots lol,,, but with that bow shootin is effortless and accurate.
I use 2016 aluminums with 125 gr tips,,draw 27",,,they bareshaft perfect for me!
I have a homemade spine tester and I use the spine of the 2016 to make my own wood arrows,,,long process but in a nutshell,,,cut blanks 3/8 square of fav wood,( i have some old fir planks salvaged that are so good in grain) i built a die out of 1/2' steel and drilled hole in it from 3/8" down to 5/16". take my shaft,chuck it in a drill and run it thru the first hole to knock the edges off,then on and on to smaller holes till I match the spine of the 2016 I've done this with numerous shafts,,,once I find a aluminum I like match it with wood, heavier woods like ash require smaller diameters.
Anyway thats how I do my shafts...
I try to keep it as handson and cheap as possible
its fun too!
