I guess because hawkbills aren't particularly wonderful in my mind, I haven't paid much attention at all to them. For instance, I don't know the difference between the Merlin and the Harpy. Knife Center sells a plain-edged Merlin for $52, with an FRN handle.
Am sure not much use trying to persuade someone with a bias against FRN, but I'm not sure what you mean when you say it "won't hold." If it is hold up that you meant, I have a Gerber LUS in Zytel, that I carried around 15 years. It can be cleaned up to look virtually new. I have my doubts that G-10 or CF will last/hold up as well. Be years before we know.
Zytel/FRN is virtually indestructible, unless one goes to smashing it with a hammer. I have yet to read of a Zytel/FRN handle breaking, or fallling apart.
I'm very pleased that Spyderco -- in 2 of my favorite knives -- puts the best steel with teh FRN handle. These are the Native FRN and the Calypso Jr Ltwt. It is really great for a company to take such good care of it's lower economic customers. One of the many reasons Spyderco is my favorite manufacturer.
If you read the forum here or the forum at Blade Forums.com, you'll read about people talking about their 10 yr old, or so, Delicas and Enduras. Some are having problems from wear -- but nobody is talking handles.
