I am still wearing the v-force profilers. However, I have tred the grillz and I personally do not like the shape of the lens when I wear them I do like the looks of them. I do not like the i4's just because they are so small and part of my chin is exposed. I have never tried the e-flex so I do not know how they feel. I have friends that use the sly profit mask and they like it however I have never tried one myself. To me the profilers still give me comfort and let me see just the right amount with my bad vision.
