I find that using high visibility braid (yellow or bright green) makes line watching a breeze. My old eyes have trouble seeing thin fluoro main line. You can see bites better and it's really easy to tell when your bait has reached the bottom. I also have way fewer problems with line twist on my spinning reels. The sensitivity is awesome with braid. I used to use a 6 to 8 ft leader but now I use double that length to allow more re-ties, without losing any of the benefits. I mostly fish for smallmouth in deeper water. I'll never go back...
