I really only like the 4 sided, or maybe its really 3.5 sided, spoke wrenches. I have a DT Swiss Spokey which is very cool but not large enough for some "Asian" nipples, heh, so I thought I'd try a Park wrench. Great engagement at the nipple but the plastic coating at the top of the loop really needs to be removed so that the spoke and nipple are better aligned when using it. Once that stuff was shaved away and I burnished the exposed metal I liked the tool better.
