I've been cutting down the worst of my 20" flight arrows to 18 1/2" to try in the latest flight bow (to avoid over drawing it too soon and over stressing it before trying at 20").
The bow is about 50# at that draw length (18 1/2" plus about 3" overdraw), Hoping to get the quarter mile

I found some hardwood, Cumaru I think (from some old garden furniture) and managed to turn it down pretty skinny 4.6mm at the tip 5.3mm at the nock (with cow horn insert), it is still fairly stiff. I haven't made the brass point yet, but I expect that will weigh about 10 grain.
It weighs 126 gn at the moment.
Does this sound just too light to you guys?
I wanted thin for the aerodynamics, but I realise it does need some weight ( the old throwing a golf ball vs ping pong ball )
All comments gratefully received.
