We get a shitload of iron covers turned in. Obviously that’s 11 or so Headcovers to keep track of… bound to lose one, percentages are too high.
I always use a putter cover now. Back when I had a Ping Anser 2 stainless I didn’t, and they didn’t sell them with the putters anyway. Now the softer putters need covers or it’ll look like a bit before you know it. Rex putter is proof of what happens when you use one. My Ping Redwood Anser is flawless as was my Anser 2 milled that I just sold.
