Words are inadequate

I was thinking about trying to generate a sheet to use for Sleuth that would have ready made on it the things necessary to neatly/easily do (well, at least the charts and stuff would be neat :) both Mark's system (which, of the systems I've seen people use, has the advantage, IMHO, of being easy to see the potential logical deductions) and my system (which is similar to yours, and one of the main advantages it has over Mark's is the potential for error recovery/rollback, double checking, etc). Although if you can just cheaply obtain additional pads from the manufacturers, or a pdf of the sheet provided, I think I'd rather not bother, since it would sort of dictate how to set up your sheet, and I think the different systems people come up with are interesting to see. Anyway, let me know if it might be useful for you if I worked on such a thing (also, what maximum or exact dimensions you'd like the sheet to have, if you care about that).
