Span-wise, I rolled them in the channel with Hysol
What sized arrow shafts did you use? Aluminum arrow shafts have a standardized sizing chart across the board but carbon shafts are sized by spine is it's hard to convert the size if ordering online
I do not have packaging any more, 500 series seems to ring a bell, anyway it is the biggest diameter they had at the sporting goods store. I know nothing about arrow shafts except they are very light and rigid.
