I changed over from the conventional style nocks to Magnocks earlier this year and if you want a quality nock that is going to leave the string with the same pressure every shot then take a look at the Magnocks.

I first got them for my target bow and was that impressed with them I got another reciever and put on my hunting bow.

I did do some work with the crono to compare the speed and I will admit that I did loose 5fps out of the bow but when I compared the 2 nock styles at 40 yrds the Magnock was 7fps faster.

They also claim that you can use smaller fletchings with fixed blade broad heads so I decided to test that theory as well and fletched up on of my hunting arrows with 1.75" vains put the Muzzy 3 blade 100 on and started shooting well they was right (I can only shoot out to 50yds at home) and that arrow was still dead on at 50.

So there is something else you can think about
But check them out the do everything that they claim them to do.
Oh and they do have a life time warranty if one breaks for any reason including being hit by other arrows or robinhooding they will replace them no questions asked.
