I’m with Flymaster, way too many lines for me and only two of them made to the American Fishing Tackle Manufactures Association standards.
Shameful.

I do agree with you to some degree....but...as a fly fisher of over 40 years...don't over complicate things.
Often...the "features" are nothing but marketing hype to get $ out of your pocket and into someone else's.
