Heard good things about them. Im know Orygun Archer like his, tho he did break one and had edge rapidly get him new ones.
MK broke one as well...they're graphite! Oars take a beating sometimes... what happens when youre graphite rod takes a hit from another rod or a tree, maybe a rock? It gets fractured!

For $750 a shaft ill just keep my fiberflex shafts and dynalites and not get shafted on buying a set and a spare... keep in mind too those edge shafts are quite a bit narrower than your standard sawyer or cataract shafts.
