This is my first Opus 88
This is my first Opus 88, plus my first flex nib, and I couldn't be more pleased with it. The Jazz is well balanced either posted or unposted, feels well-made despite being lightweight, and writes like a dream. Although I have nothing to compare it to (so take this with a grain of salt), the flex nib has a pleasing amount of give without being overly soft. I am thrilled with my purchase.
