Recommendations for Fluorocarbon line

I am planning on buying a new spinning reel and was wondering what brand of fluorocarbon line you use? I plan on using 8lb primarily fishing for walleye, northern, and bass.

I would use either 6 or 8 lb Berkley Vanish(clear)....this is probably the best stuff I've used.

Thanks Rob for the advice. I've used p-line in the past so I'll try the Berkley this year. Regards..Randy Price
