Depending on your work environment, blues may indeed be too loud. Mine (a Ducky Shine (version 1) with MX blues) is drowned out by the arguments, er, enthusiastic discussions, that occur down the rough end of the office, but in quieter moments it does seem like the keyboard is the loudest thing. No-one has complained yet
If you will be taking the keyboard back and forth, TKL would be a good idea. Apart from being smaller (and thus more likely to fit into a bag), it is also somewhat lighter.
And/or consider a special carrying case. There are a couple of threads here, and I think one of the major vendors also sells cases.
