After a very long wait I finally got my Pro Gear in rhodium trim with an HF nib. I wanted to thank the many people who have contributed in related threads.
I bought it from j-subculture, sent to LA, I usually have things sent on through friends of friends to Mexico City but in this case no one was making the trip so I had to try other means, which took about six months; the wait made think of joining a zen monastery or at least taking up knitting!
I got this pen after realizing I wasn't doing any favours to my favourite ink, Tsuyu Kusa, in a pearwood Ambition with an extra fine nib; and that my best pens had nice nibs, but nothing spectacular; my m400 started feeling downright clingy, which I was later able to fix with a few 8 figures and a micro mesh.
It's surprisingly shorter than my m400, but luckily not uncomfortably so, and its section is thicker than those of my other pens, which was also sort of the point. The nib is very smooth, probably my smoothest, and HF lets Tsuyu Kusa show more of its character, so mission accomplished, if with trepidation. I've had perfect starts and no skips. As an added bonus Kon Peki looks better to my eyes in the EF ambition than it ever did with thicker nibs - too close to Ama Iro for comfort. And as an extra bonus the ink doesn't seem to evaporate as quickly as it does in the Ambition, with the result that inks look darker in that pen after a couple of days.
The nib is big and beautiful, I must admit the first impression was "boy this feels plasticky", even my Sonnets feel more substantial, but I still find it a beautiful, sober design.
