I just bought my first home and want to install some permanent LED lights on the house. My house is fairly simple having only one floor. I'm going to be running 5m 150 light strips. I am going to install the aluminum channel, but this is where I need opinions. I am going to install along the soffit of the roof. Should I go with the flat aluminum channel which would aim the LED's downward or should I go for the 45degree channel which would aim the led's more towards the street? I want to run along the soffit to keep the amount or rain/direct sun down.

Appreciate any opinions or links you might have on this.
