Anyone ever use the new Thunderball nocking system from NAP? Is it worth it, or any better than the conventional brass nock?

I never seen it how does it work?

Magnet and steel

Thats what i thought when i looked at it but not sure. I think I will stay with my knocks.

I agree 100%. Knocks are so simple and effective I can't see how you can improve on them too much if your string is set up properly. I like the ole's K.I.S.S methodology...keep it simple stupid. Besides, if it ain't broke don't fix it. Just my .02 cents.

I agree 100% bearklr!!!

If it stays on securly it could be a great new set up. There is zero nock pinch. I like the looks of it.

I agree...now we just need someone brave enough to try it out for us.

seems to me, it would add alot of weight to the back of your arrow. Giving you a not so good FOC.

Good point...their site provides no information on the weight compared to a conventional nock.
