For what it's worth IMO, Unless you plan on 700+ mile days a russell day long is over kill as compared to a stock BMW comfort saddle (I have and use both) and the smooth 75 is hard to beat (I have 100s and 1100 to compare with). A c-3 schuberth hat is part of my kit that is light, quiet, comfortable, and convenient (I like modular design). At some point I would like to have a 75c but so far one has not crossed my path but the s that I have set up with bar backs, c bars, and comfort seat has taken me coast to coast a few times in all types of weather with nothing but joy.
