I just wanted to chime in as I can give an actual hand's on experience with this, what I think will be, revolutionary fitting system.
Over the summer I trek'ed from Philadelphia to Plymouth, Indiana with the sole purpose of working with Bruce. In addition to working on putting with Bruce, coincidentally I wanted to also make sure that the putter that I was using was right for my stroke. As I am working with him outside, the UPS guy arrives and brings out a box and Bruce gets extremely excited. I'm thinking that this is some completely custom, pimp'ed out putter, but it was anything but. The original "prototype" was a black version of the heel shafted "putter" pictured above.
Bruce then takes the putter and rolls a few putts before he hands it to me. I really don't know what to think as he hasn't explained anything to me. I put a ball down about 10 feet away from the hole and I decide to move it a bit closer (more like 2-3 feet). I proceed to not even sniff the hole from that distance even though I took my normal stroke. I look over at Bruce and he smiles and tells me to keep trying. I then miss another one, although I think that one burned the edge. So, now, in my mind, I'm trying to figure how how to make this short putt with this "skeleton" of a putter and take some practice strokes. Something in my head clicks to make more of an arc stroke and I start making putts. I look over at Bruce again and he is smiling and nodding his head.
He then explains the concept of this fitting system and the 6 strokes. I was extremely impressed and can see how this could be an invaluable system for pros and amateurs alike.
I feel extremely privileged to have been there on the day the prototype arrived and validated the system with just a couple of missed short putts. I wish you both the best of luck with this system.
