Great point Eddie. That scenario really isolates the importance of the line choice.
I recently experienced a similar scenario with a Spey tip system. When I lived out west and used the systems regularly, I was tuned into which tips are which by color coded loops, etc.
When I went ba#### last spring to fish for big natives on Cascade rivers, I had to spend a lot of time changing tips to figure out what would work or not. Even changing the front half of the taper makes a ton of difference.
