It seems that's popular, so I've modified it slightly to get this:
A softer grey on the verticals (enough to still be perceptible, but slightly less in the way), and making use of Word's diagonal borders. (Diagonal borders aren't supported by OpenOffice or versions of Word prior to 2000, but those cells will just appear blank instead).
Of course, the question is whether it's better than the old one. If it's more awkward, then it's not worth having the hit location numbers on there - many games will have someone around who can remember these well enough to call them out on the fly anyway.
I'm tempted to say it is better - even without the location ranges, it does feel a lot easier to navigate (particularly when compared to the ill-aligned and self-referential official version). I think I'll probably still make versions of my sheet available both ways though.
Expect to see that once I actually work out what (if anything) to do with the extra space from the now absent hit location chart.
