Shot the Z7 for the first time since last fall. The 3" Fusions are nice, much stiffer than any other vane I've used so far. Grouping wasn't great, 3-4" at 20yds but I wasn't really going for perfection just wanted to dust the cobwebs off. Few more days at 20yds and I have to move back to 30 and 40 to adjust my sights. I'm sure they are flying much faster with the shorter less offset vanes.
