Im getting a rangeman and debating which model. The green is by far my favorite aestheticslly, and i am a sucker for negative displays but how is the readability in harsh sunlight? I like positive display the least but i do a lot of mountain climbing and similar high sunlight activities and need this to be legible first and foremost. Anyone get either the green, or black with negative display and have trouble reading it outdoors in the daylight? Am i making a mistake pulling the trigger on the green one?
