I tried them, was using a whisker bisquit at the time and they were very noisy going thru it. They shot OK but I had to move my nock point up about 1/4inch or they would hit the bottom of the whisker. Then I got a new bow with a ripcord rest and tried them with that, again shot OK and would hit the rest unless I raised the nock. I ended up staying with blazers but now I am using the FOBs and really like them.
