I was wondering if anybody can speak from experience about different types of screens (doesn't have to be on a GS500F). With the $US at .90cAUS it's a great time to buy from overseas. Couple of brands I'm looking are Zero Gravity and Puig. What types do you prefer? Touring or double double? What tint looks better, smoke, clear, black etc. Do they make a huge difference?. Thanks for your input.
