Adam, looks like you've made your mind up between the clearview or the national but I had the clearview and whilst it was a good screen, for looks it just had something about it that wasn't right with me.
For a couple of reasons I had to change to a bigger one so I took the opportunity to buy the Memphis shades big shot. I'm a bit over 6' and for looks and protection I couldn't be happier. I've also put on the lowers which I wasn't a fan of originally but I have them on in such a way which look good and prevents to extra movement of air upwards which can occur when you have a screen.
Just my two cents worth. I also did look into the national cycle but whether it was me or not, I couldn't seem to find the answers I was after for it to fit my bike. I suspect it's all been sorted since then though.
good luck
