there are a lot of shoes in the nike lunar line up that are between the racer and the pegasus. Why don't you work your way there, starting with the newer lunarfly?
Also from my experience there is too much heel and squish in the racers to be considered a minimalist shoe, light weight yes but not minimal.
I found the softness and bounce in the shoe prevented me from feeling the ground with me feet like I would in a lighter racer from one of the ohter brands like, mizuno, saucony, or adidas. I believe that part of the minimalist idea as well. I could be wrong though.
