line recommendations for a Winston BII X ?

[Fly Goddess]

I have a Rio Selective Trout on mine -- casts just fine.

I agree, it cast just fine, then I put on SS GPX....no comparison.

I love my BIIX 4 weight... Like the Rio Selective trout also (but I believe it's discontinued... I used a DT a lot... I fish mostly smaller dry flies... I'm not into it for distance.
