I use multiple types of braid. 30# Suffix for my doodlesocking rods, usually with no leader. 15# Kastking (cheapo ebay stuff) for dock fishing, with or without a fluoro (pick a brand) leader. I also use hi vis mono when I'm dock shooting.

In my experience, you usually don't need a leader where I fish in NE OK. I think this is HIGHLY dependent on your area.
