I picked up the 9-11-13 on the Acer XDS. Had a few old SK Fiber Corsair 75 stiffs around, from when Hireko was blowing the out. They were pretty stout, so I never tip trimmed any of them, and hadn't used them in a few years. But I put one in the 9 untipped, and tipped a half inch for the 11 and an inch for the 13. They're working out pretty well. Played last week with driver, 5W, 9W, 11W, 13W, 8i, PW, AW, LW, putter. Played poorly, but not the Acers' fault. They do like to go left, and these aren't the offset ones, but I'm getting used to them. Might drop the 8i and PW this week, see if I can get around without them. If I'm playing lousy, might as well experiment.
