Yes to braid for dippin' and trolling. You get your lure back from snags a lot more often and the fish don't care a bit. On the trolling, make sure your rods have a lot of 'give' to make up for the no stretch line.

Mono for casting, especially slip bobbers.

That's my "expert" advice.

I use a Stren braid that comes in chartreuse, but I don't think the brand matters much. I used to use PowerPro yellow, and it worked just as well. Lots of guys on here use the power pro.
