Having owned both a Profiler & a Grill, the smaller lens did not inhibit my peripheral vision. The Grill has less vertical peripheral vision but not horizontal, where it actually counts. You look more to the left & right than up & down.
Also, if you remove the lenses from each mask and look at the opening for your eyes, the area is practically the same size. The added height of the Profiler lens really just covers mask area.
