Everyones definition of “mid-size” is different, I suspect, as is what’s “thin” for a topline, but I consider the Maltby MMB-17 a midsize non cavity blade with not too thick a topline. I designed it to be the most playable non-cavity “blade” available, based on the Maltby Playability Factor. to do that, the blade had to slightly longer than traditional muscle back blades and the hosel had to be shorter. We achieved a Super Game Improvement rating on it and it had been a best seller for us. It, and the TE and the DBM cavity blades, are the most playable “blade” profile designs we have ever created, and I have not seen another manufacturer hit as high a playability number on a blade category iron.
