This was an intriguing puzzle. No guesswork required, it can be done by deduction, but it was initially really tough to find the way in. I probably spent twice the length of time sitting there with the zeroes deduced and one digit written in (I think we all went there...) than I did then solving the rest of the puzzle once the deductions started to fall into place. I did actually start out trying to brute-force something with the BE/BA/BEAR/BRA combinations, and that turned out to be futile. I didn't quite get in by candledave's route, but I can see how that would work -- it may not be at all obvious why that combination of clues helps, but pondering it for long enough and eventually figuring out what you can deduce and how will provide the keys needed for the rest of the puzzle!
I quite enjoy the numerics, though I know they're not everyone's cup of tea. However, it does seem to me that one thing they lack is the ability to "chip away" at a tough puzzle throughout the week -- I can come back to a set of tricky clues several times, getting one more here and one more there, and eventually break through. Numerics tend to be impenetrable to start with, then once they break through it's a pretty quick process to have them finished. This is the first puzzle this year that I've finished within one day. I wonder if there could be a way to devise a numeric that had the "chip away" capacity of a really good word-based puzzle...
Kudos to this one for the fine set of "words" the clues formed. Someone had fun there. And a nice little endgame I thought was going to be harder than it turned out. Many thanks Hedgehog -- that was indeed just the job!
