Oh dear god, here we go again. Shorty has laid down the hammer again, prepare for war.
Was Nick's post at all modest, nope. I am sure he's a confident guy. Sometimes confidence can be taken as arrogance. We don't know what his level of perfection is. To some amateurs, perfection might be a feeling, then you get them to swing really really good, then they wonder wtf they have been doing. Not every one can be modest or humble, if that was true, life would be boring.
I can not say if majority of pros play blades or not. Since most clubs have shied away from blades, i am sure more and more pro's are playing something that is blade looking, but isn't what would be considered a true blade. Like Sergio, i saw he was playing the Rocketbladz Tour. His irons had that little slot in the bottom. He's one of the better iron players out there, and he hits something that has mix technology. Also, a lot of casted cavity back clubs are being made with softer inserts. Taylormade does this. I call them insert, but a lot of clubs have it where the grooved area is a different metal than the rest of the club.
There is so much grey area now out there, its tough to say if majority of pro's still play blades or not. Do you consider a blade the shape of the club? AP2's have a small cavity in them, are they blades? They're very much a better player irons. They are not the CB or MB Titleist puts out, but i would consider them a blade iron.
