Canal Jiggin'...what line you use?

[5 String Bass]

Interested in the fireline test too... Does the 30 lb work well for most here? I'm debating between that and a 65 lb PP or other similar braid. Also how MUCH line do you typically need to fish that little creek, known as the ditch, when jigging? Does anyone feel the need to load up more than 300 yds of braid?
Thanks.
