Michael, 2 at Trails is 214 yards and can play into a stiff wind. Either you hit your short irons a lot further than I do or you're not playing the right tees. It's a great par 3 from back there. The green is a big target, but the wind makes it challenging to hit, and those natural sand dunes are easily in play.
Kevin, that's a nice list. Of those, I've only played Merion. While Merion has a great set of 3's, I don't think they compete with Trails.
Compare their short ones (5 at Trails and 13 at Merion). 5 at Trails has much more interesting green. 13 at Merion is a charming do-or-die wedge shot, but Trails just offers more variety, more pin locations, more ways the hole can be played, etc.
Compare the mid-length ones (17 at Trails and 3 at Merion). They both have great greens, but I still think 17 at Trails is a more exciting hole with more interest, options, variety from day-to-day.
Now compare the long ones (2 and 12 at Trails --- 9 and 17 at Merion). All 4 of these are great holes, so it might just come down to personal taste, but I would prefer Trails. They all have exciting tee shots and great greens, but the holes at Trails offer more excitement if you miss the green.
Obviously this all comes down to taste. Merion has one of the best sets of 3's in the world, and I think Trails 3's are better. I'd be happy to hear others' opinions on these holes.
