A word of caution on the "all in on braid thing". I fished the Block last Nov and found out, the hard way, that braid isn't necessarily good for all things. It doesn't have the abrasion resistance that good tough mono (like Ande Back Country) does. The Block is a lot of rock and rubble and barnacles so I lost fish and plugs due to line breaking, fraying, etc. This was fresh 50# Suffix 832. I have since bought extra spools for my reels and now have one loaded with braid and one loaded with mono for all my reels. Same with the conventionals except it's one reel with mono and one with braid.
I figure I rarely catch anything when I fish with spin, so I might as well start flinging the fly. Then when I don't catch anything, I can at least blame it on being a flyfishing newb.
