As Howard Hill said, "Son, you've got to decide if you want to hunt or shoot targets," (or something like that).
Especially in Vegas style shooting, you've got to pound arrow after arrow into a target with very few unknowns: known distance, flat ground, no wind, ideal temperature. Turn all those knowns into unknowns and limit yourself to one or two shots from any given position and you've got more interesting shooting, in my opinion. More problems to solve keeps my mind more awake. When I'm shooting indoors, I'm focusing on only two things: perfect form every shot and putting the tip of the arrow on the same spot every shot. The last time I shot an indoor league, I decided to shoot it instinctively and purposely avoided noticing what spot the arrow needed to be on to hit the bullseye. My score wasn't as high, but I actually enjoyed it more, because I had to be in tune with my inner feeling that the arrow was pointed at the right place rather than artificially putting the point on a certain spot. But I don't usually play to lose, which is why I don't shoot indoor leagues very often. I don't like to have to make a choice between winning and having fun.
