Great vid Bryan. I just got a Waterman 52 1/2 and it does write wonderfully. My favorite of the modern flex is my FPR Himalayan V2 with steel flex. I have Kon-Peki ink in both and love them. My Bluedew is great but the feedback (scratchiness) is a bit too intense compared to the Waterman and FPR. Plus the sharpness of the Bluedew snags even stationery paper flicking ink everywhere. Loved the review. Very detailed.
