I am thinking about picking up a pair of square wires with the VR28 lense to have for overcast type days. You can find these really cheap now on the bay and 6pm so thought they might be worth picking up. How do the square wires fit? I have some splinters which fit me great are they close to those? Also how is the VR28 lense? I have the VR28 black iridium in some half x 's and it is one of my favorite lenses but have not tried the VR28 with the black iridium. Are they too light or are they good for overcast type days? i want something to add clarity on the dingy days. Thanks for any input I have also seen some square whiskers....any difference? One better than the other?
