LBlack14 I don't think it does actually flex, it just feels and sounds different than a traditional face, and that equates to the hot/springy feel. Hard to explain, but if you've ever bump and run with a managing steel hybrid or fwy wood and got that spring rebound like feel, that's similar to the way it feels with the prophet cb's when chipping/pitching. Totally different animal as it relates to feel/sound....I think I notice it most on mishits.
