Practice hard, and choose a pen which you feel that will give
you the best handwriting.
Though the type of pen you use doesn't not affect the quality of
the student( nah.. I just don't take that), but.. I still feel that
every student deserves a pen that suits their need.
;) popular has a large collection of pens. G2, pilot, etc etc
you name it. Go there test a while and post your feedback.
Try not to find a pen which has a very small puny size. :-X it's
gonna strain your muscles holding firmly.
Rubber grip sounds like a good choice~ but also depend on the
overall size of the pen.
