I had a DB on mine for about a year and just changed to the ST, which I like a lot more.
By the way, if you call Zero Gravity direct to order a Sport Touring screen, do not let Linda talk you out of a dark smoke tint (if that's what you want). She kept telling me how they wouldn't take it back if I found I couldn't see through it and I finally caved in and went with the light smoke only to find that the top of the screen is several inches below my head (an ST is two inches higher than a BD, which is two inches higher than stock). When I called her back to get the tint I originally wanted, she tried to charge me a restocking fee. She eventually agreed to waive it but I'm still waiting for the return to show up.
