As a I do some writing myself (and have a terrible handwriting...) here is what I can say:
1) comfort is really important, so if you give your son a pen, do not expect him to use it for his writing;
2) Moleskine is not FP friendly;
3) I agree it would be a good idea to ask him about his writing habits/demands/preferences; for that price you can find very nice pencils.
4) be aware that buying him a FP can lead to many FPs in the future... 😎
Just my two cents of course.
