I'm thinking of buying a nautilus reel but need some help. I need help deciding between the nautilus 10 and the nautilus 12 to hold my spey line. I have a 7/8/9 windcutter. I have found where people have said they use the nautilus 12 for this line, but they also use 250yds of 30lb backing. This is over double the backing that I would like to use. Does anyone else out there have one of these reels? Will the nautilus 10 hold my line plus about 75-100 yds of backing?
