I'm assuming you have a OEM Tourer shield too...
The "really good" thing about your OEM shield is the almost
irreplaceable hardware.
Clearview make a real good replacement for the plastic...
If you didn't have the hardware, Memphis Shades makes
a shield+hardware for the Valkyrie called a Switchblade,
I've seen them on some really nice bikes...
This black bike has the Memphis Shades, and that's my Red bike behind
it with OEM hardware and shorter-than-stock Clearview plastic...
