The Zebra G manga/comic nib from JetPens is the first flex nib I really got familiar with. It's large, so it holds a fair amount of ink; and it's on the stiff side, making it good for beginners and those who write with a heavy hand. Because I started with this I find it the easiest nib to work with.
Here it is on the Tachikawa nib holder, where you can appreciate its size.
Participants of the Nifty Nibs workshop will get a different, more classic flexible nib. But this will be for sale in limited quantities at the venue. ;)
