I think it's great that you're focused on your future. I hope the sponsorships come through for you, and that you're able to make a go of it. I wish I'd had that much direction when I was 12!
I own several Shimano's, including Curado 200E7, Core 50mg7 and Calais DC. I also own some Abu, Revo S (last years model, not good) and Premier (this years model). Personally, I'd go Abu for the reels. The Premier's are just great, great reels, especially for the price. I'd put them ahead of my core for performance, smoothness, drag power and versatility. They do weigh slightly more, but I don't notice the difference. The Curado's are good reels for the money, but nothing special. Not overly smooth, but they do get the job done.
I've never used Abu rods, and only one Shimano rod. So can't really compare those for you. Maybe try to get a sponsorship from Loomis, too? :-?
