I recently bought a fountain pen I've lusted after since it was released. I bought the Sonnet Firedance,

red and black laquered finish over brass, 18kt semi-flex fine point nib, and was utterly thrilled with it till the following year when Parker released the Chinese Ambre Laque finished Sonnet. It had the same 18kt nib, but this one is two-tone white and yellow gold, the cap has a wide gold band rather than the narrow one on the Firedance, and the laquer has flecks of gold in the hand-painted finish.

I've loved my Firedance ever since. It writes like a dream, the nib giving a nice narrow line on the upstroke and a broader line on the downstroke. I had to do a lot of handwriting in my job, and my Sonnet was a workhorse for many years. Still, I coveted the Ambre Laque.
It is now mine. I've spent some time just holding it, clicking the cap on and off. For two pens made to the same specs, from the same materials only with different finishes, the pens have a different feel in the hand. Imaginary perhaps, but perceptible. So, I've held the new pen, eased the cap off and on, posted the cap, held it in position to write.
Who knows? I may actually dip the nib tomorrow. And fill the converter this weekend. We have to get aquainted. This will be a long and hopefully productive relationship. Can't rush these things.
