Scientific Anglers Amplitude Trout Series WF 6 Weight to trade straight up for same in a 4 Weight.

[scottywest6]

I have a brand new in the box (box not perfect but line is absolutely brand new) Scientific Anglers Amplitude Trout fly line in a WF 6 Weight that I would like to trade/swap straight up for the same line in either a WF or DT 4 Weight in brand new or barely used condition. I would also consider a Scientific Anglers Wavelength Trout fly WF 4 Weight or possibly (but not preferred) one the older Scientific Anglers Mastery Textured Trout in a WF 4 Weight as long as it's also brand new or barely used condition (in the case of the older Mastery series it would need to be new). Have no interest in either the Sharkskin or Sharkwave lines.
