Lee,
Excellent! I hope you enjoy the Hero 395 pens more than I did; to my recollection, they wrote too broadly for my tastes and my regular handwriting, but the model seems to have a few fans because of its supposed 'semi-flex'.
Yesterday I started playing with the couple of Jinhao X450 pens that came modified and fitted with Zebra G nibs. Those nibs have been mentioned here quite often as good for English calligraphy, and marrying them to fountain pens to provide an ink reservoir makes them more convenient to use. They cost me about A$7.50 (including GST *sigh*) pre-assembled to order from China, but now I also have a bunch of 'spare' X450 pens (complete with what I deem to be Medium nibs) and Zebra G nibs ordered separately. You might be interested in trying something like that some time; the X450 sections have a faceted, triangular grip, which may or may not help with your question about changing your grip.
I also have some 'spare' Pilot Plumix pens with CM (Calligraphy Medium) nibs, which are good for italic writing. You can order them piecemeal reasonably easily from Amazon.com.au; I ordered them in 3-packs shipped from the US. I usually take their nibs and transplant them into Pilot MR and Prera pens, but the Plumix pens are usable in their own right if you're not too fussed about portability; they're quite long and clipless. Actually, my fiancée took two of those – housed in a leather pen case – to her book-signing events, because her book is a children's chapter-book themed around a comet, and the Pilot Plumix and Penmanship pens have comet-shaped bodies, so I thought the kids would find it fun to see. They served her quite well.
Anyway, let us know which hands in English calligraphy you're interested in. As I've mentioned elsewhere, I'm open to organising Round Two of the PIF of pens and inks for Australian users.
Cheers,
Dill
