I used micro-locks I believe they are called. Not a big fan of them though after having to play with wire to get it to lay straight after crimping stopper on the backside. Also I would recommend using the mini deer lock nuts instead of the clip on's when I do it again.
Brian certainly helped me out with reducing the learning curve. For anyone reading that's wanting to get into this I've had all my success putting snares on the trail heads on the field edges. I put em in thick at pretty much every trail head I see at a pinch point on the trail.
