Best line for River fishing walleye/pike/etc

[Easywean]

Hello all,

Just wanted to get an opinion on what line you think is the best for fishing the rivers for walleye/pike/goldeye/etc....

I mostly fish the Red Deer River. Throwing spoons, rigs, rapalas....nothing too huge. Right now using Stren original low vis green mono on 3 spinners and clear Stren mono 8lb on a baitcaster (that's what it came spooled with).

Any input appreciated! thanks!
