Weak furrel design with six slots cut into it and the blades are easy to bend if something heavier than a rib is encountered, such as a block target.[&:] After I shot them into the targert and the blades bent I didn't bother with them any more. They were accurate though.
If you want to try something new that is tough as nails and really does have great flight characteristics you should try
slick trick broadheads. IMO it's the toughest head out there today and flys better than any other broadhead I have used thus far. They are $20.00 for a pack of three which is $10.00 cheaper than the tallons and are a far superior broadhead.
