Agreed that the Arai works well, as I’ve used both GP and SK models with the Leatt. Recently I’ve been using a Shoei X12. There’s a little more clearance, and the ventilation is better. However, the x12 feels a little heavier, as Arai isn’t blowing smoke about being able to keep the weight low in the shell. Very little acclimation was needed, though, and I’m very satisfied. If you go the route of the x12, I can forward the vector file I made for the visor strip.
