Nice, these give me some hope. I am still working on getting my set up all together, just finishing up my arrow spine tester. Got myself a 3/8" Veritas dowel cutter so I can cut myself some square stock from straight grained board, then run through the dowel cutter and then test them out on the spine tester. Do you know what they spine or just weight matching? I know you said they shoot best out of your 60# bow.
