I've been enjoying my Rufus for over a year. Probably approaching a 100 rounds on it (I don't track super close alas).
And maybe I'm just not aggressive enough, but I wouldn't be able to carry four putters up top in a round. I toss four up there for field work sometimes, but they don't settle down in the slot properly when there's four.
At times I think about trying out the Squatch equivalent of the Rufus just for the bigger putter pouch. But then I remind myself how much I've enjoyed the Rufus, and that it's nice to support US manufacturing, and that I only need two putters and an approach disc up there anyway.
