One of my local retailers finally got one of these in a few days ago. Honestly, I was a little underwhelmed. I am a PING guy and the TR grooves are legit IMHO but this putter felt harshly firm to me. I also generally prefer a milled face to an insert however I think that the Sigma G Tyne H has a better feel and roll. I am not mad about the Tyne H having a headweight of 370g but feel and roll wise, I think it is the best toe hang mallet out there right now and it is back in my rotation.
My misses are misreads, more than mishits.
Plus one more in the bright sun...I still love this putter!
I also finally got mine in from PING , took 4 months to get here because I wanted a different hosel for a sbst stroke and a stealth shaft
