Does wedge flex matter?

It didn't hurt my game at all and my situation is opposite. I used to have a set with regular flex shafts that came with a sand wedge that was regular flex. I got new wedges and the shaft was stiff(S200), but my new irons are reglar flex(R300). I could hit my old 56 farther than the one I have now, but I have much better control with my new one.
