They also have the new ones that are a lot more flexible than the original. I toyed with the originals (liek they have at Cabela's now) whe they first came out the foung them to fly extremely well after setting the nock just a bit higher than normal. My only problem was that I'd break them really quickly if I shot groups even at 40! Kind of a good thing but I went through a ton and waited till the new ones came out. Just placed an order for more yesterday
