It's a mallet, so it's face-balanced, which is probably best for most of us (like it or not.) Even "The One" only opens and closes his Scotty Cameron 1 degree through the stroke, so a face-balanced putter is more likely to help keep all of us duffers putting a little more squarely down the line. Mine has the black plastic insert - newer versions come with a variety of inserts, and choosing your favorite is really a matter of feel. I suggest, though, making sure that you choose one with alignment markings the same as mine - I find them to be the most intuitive, and they help keep my eye right over the target line - just keep the single alignment mark between the two lines on the back of the head, and you know you're all square. The new slightly larger mid-sized grip seems to take my wrists out of the stroke even more.
My regular playing partner uses a newer Ping blade, and seems to be able to drain it from every where, hence is golfin moniker, "The Blade!" (Yes, it is spoken with the exclamation point when used. Such as, when he rolls one in from just of the green, 25 feet, through a double break and a half-dozen untended pitch marks into the can, his partners are obliged to call out "The Blade!" in salute and recognition.)
Such feats appear even more amazing when one considers the, shall we say, unorthodox putting stroke that he employs. It's a distinct out-to-in jab at the ball (it's the kind of stroke I'd use if I wanted to slice putts) which leaves his opponents even more incredulous when the damn ball roles straight to the hole. I have never and will never tell him what's wrong with his putting stroke - I might ruin his putting game and send him back to bowling with his spouse, "The Decider." I have to guess that the toe-balanced Ping must enable him to square up the face about a millisecond before impact, and just enough to counter the angular, glancing blow such that a straight roll of the ball somehow results. It's a wonder to witness in person.
Ol' Rossie is weighted just right - heavy enough to stay stable on short putts, but not so heavy to remove feel from the longer ones. While the face is a plain-jane flat plastic insert, face it guys, all those grooves and inserts and doo-dads that are supposed to impart top-spin or other effects don't really give most of us what we need... Guys that I play with really need to keep the club on plane, face square to the target line at impact. A millisecond of putter back-spin isn't what keeps my handicap in the high-teens...
Still, if you gotta have the newest so-called technology, there are more than a few mallet heads that look just like ol' Rossie, and they come in a variety of face configurations - perhaps you could find the best of both worlds. Me? I got my fat and sticky grip on my old stick, and I'll be out there showing The Blade what ol' Rossie and I can do this season...
