For exams and heavy writers the 146 is recommended, since its weight and girth stabilise the script and reduce the pressure feeling on the middle finger. The slimmer 145 is also well suited but for extremely long writing sessions less ideal. The 149 offers maximum support in the hand. As nib width F or EF are recommended, since they enable more text per page and make the script better readable; depending on individual handwriting M can also fit. From the Mozart (114) heavy writers are advised against, since its slim and short shape leads to cramping during longer writing; it is suited above all for notes on the road. As source, primarily specialist trade is recommended for trial writing; online (e.g. scription) prices are cheaper but trial writing is omitted.
