I just put new blades on my new VX and love them!! I bought the Anco winter blades. They seem to have a bubber boot over the blade hinge/spring areas to keep out the snow and ice build up in the bad winter days. Look real effective and this winter I will find out!!

But I used one 16" and one 24" and they seem to clear the windscrren very well!!!

by the way, I also used Rain-x product on my windscreen and wow!!!
The water beads off. I was driving home last night in a medium rainstorm and realized I didnt have my wiper blades on!!! At 60mph the water just rolled off the windscreen and my vision was clear. Then I turned on the wipers and though there was visual improvement I could have driven with out them safely!!

Also noticed during pesky drizzles the water just rolled off!!!
I haven't used Rain-x since the 80's, but it still is amazing!!
