There are pros who subscribe to the Pelz putting stroke. It seems to me, however, that the only way to have a perfectly in line stroke, without doing some kind of manipulation, would require having a shaft that is perpindicular to the ground. You can't do this legally unless you put your putter head in enough of a "toe down-heel up" position to make up for the minimum 10º bore angle required by USGA.
