I have found in recent months that, for me, toe hang is first and foremost in what putter I use. For instance, I have a Studio Design 3.5 which is a mid slant neck with a toe hang of about 4. It just fits. So, I had my newest Byron made with that toe hang even though it's a longer round neck. Plus, I sent in another Byron with a rincon neck to have changed to the same toe hang. I feel like I could pretty much putt with any style of neck or head as long as the toe hang was where I want it. Thoughts on this?
