Tinker I don't think blade like is the way to go, myself. I've found cavity-back wedges to perform much better, even the SW. I've read some of the so called 'experts' speak to the same. Their reasoning was that if you can hit blade wedges, you should be able to hit all blade irons. And we know that is not the case. I have both types, blade & CB wedges, but you will find the CB's in my bag.
This 3391 AW head looks like it would be a great SW, with that sole & bottom weighting, but I was looking for a nice AW head.
