I would do Mon, Wed Thursday, for the public holiday reason, as well as that way you can get some longer weekends with the Friday, Sat Sun in there and having at least 2 of the days in a row means that if you are having a bad week at least it won't drag on!! A bit different but I worked a Monday and Thursday the other week (normally Wed,Thur) and although I liked having worked one day and then having a few off it meant the week really dragged on for me!
