The airfoil isn't different. Surface finish/smoothness is. From what I recall, the higher reflex numbers are driven by getting a Cl as close to zero as possible. Based on discussions with Mark, the higher reflex was more important for the not as smooth bagged wings. It should help the molded wings as well.
There was a significant difference in zooms with the additional reflex on my Supras - easily seen from the ground. So I would expect that if the Maxa has similar characteristics, it should be noticeable by trying different reflex settings for the zoom. It appears that Kyle already found this to be the case . . .
