ok I have been tying flies for a while but mostly Big gawdy salmon flys and alaska rainbow patterns which are easy and fun to tie...But In march I will move yet again to the lower 48 so I have all winter to tie dries and nymphs for my new home.

first of all what does #1 #2 #3 mean on the hackle packets im asuming quality and dose it actually pay to spend 2x the price for the #1 instead of getting #3

second of all what is the different from the neck and saddles?
