This puzzle is just so great.
Really loved how the NVX corner worked out, and how the LX and PF corners built up the right side of the puzzle. One of those typically great Pentominous puzzles from Grant, where I was already mentally crafting a comment during the solve..
..until I hit a wall that I haven’t been able to get past, after a few days of repeatedly coming back to it with fresh eyes.
I hope this is OK to post here, here is where I’m stuck, can anyone help me find the next logical step that I’m missing? (partially-filled spoiler) http://imgur.com/1RmV42A
