I was a member at Silloth for a few years, so I got to play this hole in a wide variety of conditions, and across a range of such conditions, the hole exhibits a huge variety of challenges. It is also interestingly set head to toe (although more or less opposite ) to the par-5 14th, and the contrast between the two is often stark.
I have played the 13th as a 3 wood and 5 iron, but also as a driver, 3 wood and 4 iron (just counting those rounds when I was more or less on the fairway, I have also played it as a driver, wedge, wedge, wedge etc).
I think it is a great hole and rarely easy. The tee shot is sometimes deceptively simple, but the second and third can be beastly. In calm conditions, as rare as those are, it is perfectly possible to hit 3 wood, mid iron and wedge into the heart of the green, but even then you are never complacent until the ball is holed.
