I'm generally not a fan of Sudokus that use letters, as for some reason I find them harder than numbers (even though they are logically the same... just the way my brain works, I guess!).
However, this was a very satisfying solve - pretty difficult (though partly that's due to the sheer size of it) but always with a clear through route that could be found with a bit of patience - and with some knowledge about some of the techniques that can be used with irregularly-shaped sudokus...
