This is for a software product website. The typeface in question is used for the navigation menu, taglines and section headers. The main body font is Arial.
After shuffling through a lot of types I have converged to FF Din Medium. It has clean and precise geometrical feel to it, which is exactly what’s needed (the “real-time or ..” header):

I was very happy with the result, but then I woke up the next morning and the lowercase L felt wrong. Too playful and distracting, especially in a longer text. So now I made two alternative versions, which I think fix this problem, and I am now stuck deciding between them :)
First is a pseudo small caps. 16pt R in medium followed by the rest in 12pt bold:

Second one simply has the lowercase L straightened up:

So .. which one ?
