I would get on a blind bale with any arrow that meets bowyer's gpp recommendation. I would not put a target on it. I would make sure my form is accurate by practicing the same routine on a bale. Having the right form will make your bareshafting technique easy. You must have the right spined arrow for your bow to shoot to it's potential, but you must have the right form to shoot well. Believe me, I learned this the hard way. It was very frustrating, and made me almost want to throw in the towel. I developed much better form after watching Rick Welch's video. I bare shafted. Built my arrow's according to the bare shaft, and am very happy with the results. It is satisfying to go out and shoot well every time. If I have a bad shot, I now know that it is a form issue, and not an equipment issue.
