Merino is expensive and 200 wt is on the thin side. I believe 260 weight is considerably more durable and warmer (the warmer part is not usually a good thing). My advice is stay away from merino if you have cats (you'll forget, pick one up and then kiss your favorite merino shirt goodby). And don't wear merino when you will be bushwacking through scrub oak, which can be hard to predict. Or you can learn to live with holes.
I probably have 15 days on a Mondo zip and the waist seam is unravelling a little, but it's not a big deal. No holes yet. Cats completely ruined another brand of merino shirt, but I'm sure this is not brand specific.
