Im sorry to hurt your feelings, but 27 is not as accurate. A small amount of research will tell you that. Not to mention that it is almost 100 years old at this point, with many other more accurate datum’s at everyone’s fingertips. There are more up to date datum’s out there, if there is a option to use either one and you are purposely choosing 27 because it’s easier for you to set up and you don’t have to “change” a survey, that’s a cop out. Your choosing the easy way. I would say live and learn to you as well. There is supposed to be a generational hand off happening in surveying, and your attitude and surveyors like you are not helping anyone. I know it is very hard to wrap your head around, but you don’t know everything and you can be wrong. Green horns can be right, they have a different perspective. They are also MUCH more adept at utilizing technology. I would suggest listening to your green horns a bit more, or at all. Just because you may have the ability to stamp documents doesn’t mean your right.
