The Daedalus is a neat idea, but I've used G nibs on dip pens, and while they can provide more flex than an Ahab nib, the tines are pretty sharp, and I find they scrape the paper more than an Ahab or a true vintage flex nib.
Hopefully someday someone will come out with a new design that offers a genuine vintage flex nib experience without resorting to manga nibs.
