Noodler's Ahab Flex Nib Fountian Pen

My sister gave me a Noodler's Ahab for my birthday. It has a flex nib, although you have to push down quite hard to get the thicker line. If you're used to flex nibs for calligraphy it will feel tough, although there is never any issue on the upstroke like you have when you're using a calligraphy nib.

 Thought these trees would be fun for a Holiday card.
The Noodler's Heart of Darkness ink is a joy to use. Got the big bottle and it came with a free eye dropper pen. So that's fun. :)
