My name is Chad and i am addicted to nice reels. I'm getting the 0 for my 3wt, should fit nice. I put my 5wt line on my #1 last night. It fit great and had plenty of room for backing. About 75 yrds or so. I am sure that my #2 will hold the 7wt line I only want about 50-75 yards of backing on. The trick will be if I can get my 9wt line on the #3 that is only rated to a 7wt. I think it will fit fine I only want a small amount of backing. I fish musky not saltwater, no big runs.
