Solved my first 5x5 in 1:54. At first I thought it would be really difficult but then I found a hex which could only go one way (a corner hex with V shape) and then from there the adjacent pipes could only orient one way. There were a few times where I had to think down a tree of possibilities (if this hex goes like this, then this hex can't possibly fit here because of a previously solved hex, therefore it must go like this instead), but never more than one or two steps. All in all it's a very satisfying puzzle format.
