These are Easton Powerflight 300s that have wraps and custom fletching. They have 100gr brass inserts installed for a test that I was trying for my longbow. They have been cut to 29" but the brass insert adds a quarter of an inch for 29.25" overall. As it turned out they were still a little too stiff out of the 55# @ 28 (I only draw 27 so I was only pulling 52-53#). Someone with a heavier bow 60-70 these might just be the arrows you are looking for. Becaused they are used, I'll let them go for $75.00 or best offer for the dozen.
After taking a closer look, one of the arrows has a bad feather. It won't hurt it's flight but it looks bad. I'm going to lower the price to $60 to your door.
