Reducing Streamline to 15% to a overall 75% yields the exact same result as having it maxed.

So there is indeed a hard-cap of 75% in place.

Feel free to combine helmets and the two mods however you like, but if the final value is higher then 75% you basicly waste points.

Keep in mind that you can invest more points into streamline to get rid of some of the duration malus, but i would recommend to specificly use the fleeting expertise on build without any duration in them anyway.
