I prefer my D line P2's as absolutely beat in as possible. Current putters are the original 2 I bought back in 2017, so a good solid 4 years of thousands of putts on them. Stock stamps completely worn off and they are down 3 grams from 176 to 173. IMO they get grippier, straighter, more glidey and just better with age. They've also survived 4 Michigan winters now. I don't throw with them EVER, strictly inside C2 only, so they've never hit a tree, at least not with any force on them.
Originally putted with beat up KC pro aviars. Great putters but I broke way to many once the temps drop below 45 or so. Started with using just the P2s in the colder months Oct - April to save my aviars, but enjoyed them so much I just switched permanently.
