Probably the main factor is how tall you sit in the saddle. The Triumph screens don't seem to work very well for taller riders. The Summer Screen starts getting unpleasant for riders over 5'8". The Roadster Screen slightly taller. If you are anywhere near 6' tall, don't buy either. I don't know about Memphis Shades, but both Clearview and Windvest have a money back guarantee. I bought the Summer Screen and on my ride home realized it was not going to work. The dealer woudn't take it back. I'm currently waiting for a Clearview replacement that is taller and will fit the factory brackets. It will be the 4th screen I've tried, but I feel confident it will be the best compromise for me. I'm almost 6'1".
