Blade vs mallet pros and cons.
I use a mallet yes Madison .. Ugly as sin but sinks putts. My stroke is straight back staight through, I am open at address as well because I know my swing line. On short putts or fast putts I play off one foot ( the back one) on long putts I play off the front to stop coming up and delivering glancing blows. I would play a bladed putter and have in the past, but lining up is hard a 2ball blade would work but I am not keen on the inserts. I love the c-groove thing, I can really feel the ball.
Basically if your a fan putter a blade suits, but to be successful you have to be extraordinarily talented! A putter is a tool and you should play a max of 50% of your shots with it, so choosing it because it looks cool, should be at the bottom of the list. A simple swing that eliminates room for error ie straight back straight through will always score better due to its simplicity ...
As for distance control erm no difference this is a feel thing, why should it be better with a blade? I don't understand the logic of that argument. Especially when the word feel is not about the head performance but as in your ability to feel the required strength to play the putt.
