RE: What Shoots........
Seriously on the jig. It's not a fancy contraption, but your bow has to fit it to be in the competition. I don't think there is a 3-piece made that will pass. Really big risers like on some of the 21st Century bows won't pass either, nor radical defelx/reflex if I remember correctly. Pretty sure they have relaxed the rules some--I think in the past your bow pretty much had to be a Hill style.
Some of the best shooters in the US have competed there, and I expect they will continue--I guess they just want to keep the shoot on an even keel. I want to shoot it for the heck of it, and see some friends out that way.
The KK is a great gathering, with two challenging courses and it's non-competitive. Scorecards are issued if you want one, but you don't turn them in. We usually keep score just to rag on each other, or have a "North vs South" competition amonst ourselves.
