I hit the 52 and 56 in 10S today side by side with my RTX4s in the same lofts. I took about 10 swings with each club on a foresight and I found each club performed almost identically, with the Jaws having slightly more spin, about 500 rpm, on comparably struck shots. Distance and peak height was virtually identical. I was not a big fan of the MD3 wedges I have, so it was a bit surprising to me for the MD5 to be so closely comparable to the RTX4s, which I love.
