mike, did you have another set cnc'd by someone else, if so do you know the difference?
No I had the one set of W-9s cnc'd and a set of B1mc cnc'd, Ryan did a hand port set of W-9 that were a couple cfm better than the cnc'd ones but with the little work I did on my cnc'd W-9s they were almost identical in max flow (plus the one head that Chapman also duplicate was cnc'd)
