What Brand makes short speed knocks?

[wahoohunter]

Hello all, this past hunting season I began using the short speed knocks that are about half the size of a typical knock. I've been very satisfied with them, however, I'm not sure which brand makes them or where I can get them...I was hoping some of you use them and could point me in the right direction. Thanks for the info

QAD makes them, they are calle the Tune-A-Nock I believe, I use them and I love them, for the sole purpose of using a super short D loop.
