RE: Sponsorships at the worlds?
Yankee
Being a great shot helps but it is not necessarily what the companies are always looking for when they evaluate potential staff shooters. They want a person who is outgoing, knowledgeable and are passionate about what they are doing. After all you are in a way selling their products.
Things that look good on your resume other then high scores and wins are volunteering, different organizations and clubs you belong to and especially helping out the new archers and youth programs.
Make up an archery resume and send it into some of the companies that interest you most. I can send you a copy of my resume if you would like to look it over for some ideas of your own.
Sponsorships are not that hard to come by if you really do love shooting and archery.
I would be glad to help you out if you have any specific questions.
