anyone use the nap thunderball nocking system yet?? i havent heard anything about it...could have missed it here though...

its a magnetic half moon on your string, and the opposite half moon as your nock...i seen it on display at dick's sporting goods....

just curious about it....dont think id switch unless its the bread and butter of nocks...but curious to hear about it

Looks like a great nock system to me. I've been expecting some feedback from folks on this product since we seen it's intro in Jan. Anyone???
