I now have braid on all my spinning reels. I love it even for light tackle, but I tie a leader on, it doesn't really matter what kind of leader, for different applications I use different things. 6# p line green in the creeks and 10-12# flouro carbon on the lake.
I tie it in with a double uniknot then reel it up near the reel so my leader is about twice the length of the pole. This give me plenty of chances to tie on before I have to retie a leader. Always keep braided line scissors with you.
Buy good braid that is slick, I like power pro, or spider wire. Both bands are have some kind of coating that seems to make them more smooth, I am sure every band has something about the same. When I first began this braid journey, I thought I would save some money and go with academy brand all I can say is don't do it, it is strong enough, but it is like a dang saw going though the eyes of a fishing rod.
I try to store my rods out of direct sunlight this seems to make the line last longer. My trolling poles have had the same line on them for a year, when I used something other than braid (for trolling) I would have to change it every other trip.
Sensitivity is awesome, castiblity is fair, but you get used to it. It casts better when wet.
So far so good, all my poles have it.
