I own both...actually I own those two, a double bubble and the stock screen. I use a screen based on how I plan to use the bike. On long trips 1000 + miles nothing beats the Sport touring screen as far as protection goes, but over 120 mine starts to rattle. I believe that because its thinner than stock and sits so high. The Euro screen is a nice anytime screen that provides a lot of protection, and overall I'ld rate it above the Sport touring screen. The only reason I don't is because mine doesn't fit exactly right, seems to be molded improperly. But i had it painted to match the bike before fitting it, so i'm stuck with it. The double bubble .... I'll let you know a bought it used at a great price and haven't installed it yet.
