very ez hard with URs

agreed - 2 URs unlock it

I just used pairs and triplets to solve it. Since some consider URs to be an invalid technique, I try not to use them except on an expert I cant otherwise solve.

I guess I consider UR valid if it works. But it certainly possible that it might not.

The UR method only works because publishers are averse to puzzles which have more than one solution. Imagine pronouncing that two possible answers are both correct. I prefer to use methods other than UR in case I encounter a non-conforming puzzle.

Did it, no greens, no guess. Some pretty hairy tricks. Dont try while sleepy.
