As for what kind, without a relocation, alot depends on what your preferences are.
I have a Plexifairing III which is a large
shield that has lowers (extentions to the shield that extend down beside the forks) as well as somewhat decent hand protection. It's great for cooler weather, but can be a bit too much when the temps start going up.
It is tricky to get it on and off, seeing as it wraps around the front signals, but it can be done without removing or relocating them.
I have had a buddies smaller handlebar mounted shield on which worked good, but I have no idea what kind it was.
