This puzzle is a test more than anything else.

1) One of the imperfections of my puzzle generator is that it consistently skews the interesting solving techniques to the end of the solution. As you've discovered, this means that most puzzles start with many Singles to resolve. Some people use the Singles to get their thoughts prepared for what's ahead. Others find them a nuisance. For this puzzle, I'm going to post both the original puzzle and it with all of the initial Singles resolved. Comments are welcome.

2) My puzzle generator often creates puzzles that end with only a few semi-difficult steps. This is good for those who aren't advanced players, but it isn't enough of a challenge for the advanced players. The plus side of having skewed puzzles is that there are often alternate techniques present later in the solution. If you find a puzzle too easy, then please feel free to search for an alternate solution. I don't make any guarantees about what exists as an alternate, but I'm interested in what you find. Again, comments are welcome.

This one practically solved itself, with a number eliminations made while filling in the grid, followed by an easy-to-spot XY-Wing.
