I'm curious about these as well. I just saw some Black and Tan arrows for the first time a couple days ago. Kid walked into the bow shop with them. I did not think Easton made them though. The shop owner told me some old lady made them (probably fletched them was all) and sold them for something like $35 fletched for the dozen.
The arrows I saw were black with a tan translucent film over them. The kid needed them cut to length, so I took a scrap chunk and broke it over the table edge. Construction looked similar to a Gold Tip.
I can't imagine they are that straight for the money, but at that price they'd make some good arrows for the kids and wife since they tend to loose quite a few.
Anyone know anything else about these arrows?
