Archery accuracy is all about form. Although indoor 5 spot shooting is kind of monotenous, I think it is the best practice for when you move outdoors and hunting, especially at longer yardages. BTW, for the last few years I've shot 2613's, x-7s. I'm not sure if they make a bigger arrow yet. They are a little tricky to tune, you have to use huge point weight to soften the spine of your arrow. I use 220 gr. Sometimes they can hinder you, like if you are in a shoot off, and you are shooting for inside Xs for a tie breaker!
