I've never "filleted" a trout of any size ever......you don't fillet trout.....you cut the head off and then gut them. Then cook them up whole and after that take the skin off (if you so desire) and then open them like a book and pull the backbone out. Easy.
If the trout was really big I guess one could make a case for "filleting".....say a 10lb. Rainbow or Steelie.
If the average size of the trout you catch is 17 inches......you are doing not bad at all.......
Most of the 15 inchers I ever get end up in the frypan......
