Well, grabbed a few Walmart carbon arrow shafts... 31" @ 9.6 grains per inch, but no spine weight is specified(Just a range from 40 - 70 lb draw weight.), for 3.50 a piece.
Put 125 grain field points on for now, and fletched with 2 full length feathers in a spiral fashion. Let me tell you... at 20 yards, these things start to drop like a rock. However, within that range, they fly like absolute darts. I can group these better inside 20 than I can with my regular arrows.
The spiral fletch job was a real pain, and didn't realize until the second arrow that I should have sanded down the spine of the feather for easier application. I've got more drying time into them than anything, but they are a blast to shoot and loud flying through the air, lol.
Worked out to be about 5 bucks an arrow all said and done.
I used permanent marker to "paint" my existing nock red to match... good enough, ha.

They are a little ugly, but everything seems to be holding well... not sure how much it weighs though, 435 with arrow/nock/tip, but unsure on glue/feathers/insert. I'll get it weighed next time I'm at the range.
