Sink Tip or Full sink line? That is the question.

A line for big river streamer fishing.
To go on an 8wt rod and reel has good disc drag. I want something for fast sink because the river has very strong current.

I don't do much streamer fishing so this will be somewhat new. The whole sinking line experiance should be interesting.

Also any advise on a good brand to go with would be appreciated.

tks Yaf.
