I took a doe with the originals this fall & it performed as good as any other. dead deer in less than 30 yards. They have a Tekan 2 now that adresses the blade retention issue somehow. I have some but theyre still in the package. They look a little different but I cant say how they improved them. I'm mostly hunting from blinds now but if I get a shot not thru the mesh I plan on using a tekan tipped arrow.
