I was looking at the RIO AS/SS line at my local fly shop but my fly shop owner really does not know enough about spey rods and lines to recommend one over the other.
I want to use my own sink tips I have many of them.
Mid Spey and Long Delta also are also candidates.
Which of those 3 lines requires the least amount of reel line capacity ?
God I love the precision of this spey technology !
Maybe you do have to be a rocket scientist.
