I am not a real huge fan of the FLOGs, but I put in my stuff for my GTD event that I am doing. It is better than having to open up an excel file and put in the yardage for the day.
I've still been updating the Excel file because I'm a nerd and I love all the graphs Mary put in the Excel template!
I'm also a super nerd and am using the excel GTD spreadsheet AND flogging AND would also be blogging if I could think of something interesting to write about these days
