Everything I've added to the bow, I've paid out of my own wallet, sacrificing going to the movies or eating lunch. The only thing my mom and dad has paid for was the bow itself. I had to give it up because range fees and upkeep of the bow was getting too expensive and school work was taking up more time for me to compete competively. All through my shooting, if I've learned one tactic that really wins, it is consistency, consistency, consistency. Sure good form is really really essential but if you can't reproduce that good form over and over, you can't get that tight group.
Equipment is a factor in winning , but no one has won tournaments on equipment alone.
Take one arrow at a time. When you shoot, you don't shoot three arrows per end, but one arrow at a time. It's a great feeling when you are in the Zone. You draw back and exactly when you want to release, the clicker goes off and you nail it in the 10 ring. You develop this pattern where your like a metronome and you shoot in a cycle.
