I own two Frontiers and a NuCanoe Pursuit. Love them all. I prefer the Pursuit for fly fishing because of the four rod tubes into which you can store fly rods out of the way. However, the Frontier also is a great fly-fishing vessel.
I used to own a fleet of Jackson Cudas, but had clients flip them over on two of the first three trips. You will not flip a NuCanoe!
The stability is unparalleled. In fact, you can easily stand and cast a fly rod.
I have owned and fished out of many brands and models of kayaks over the years, so I know them all.
I love my NuCanoes. They're the best kayaks for fly fishing out there. The open, uncluttered decks are great and great for fly line!
