Braids with a fluorocarbon leader is the only way to fly for most types of fishing. The braid will transmit even the slightest (no stretch) tap on the the line (can almost tell when the fish is LOOKING at the bait ) while the fluorocarbon leader (I use about 3 feet of such) makes it just about impossible for the fish to see the line attached.

The trick to using braids is to...
1. First spool on some mono on the bottom, maybe around 10 to 20 yards as backing. This does several things like not force to you use a lot of Braid (can buy the 100 yard spools) and help keep it form digging into (very important) the spool.
2. Manually close the bail on your spinning gear after each cast to help prevent line twist.
3. If you do get a line twist (wind knot), do not open the bail on your spinning gear... Just loosen up the drag (with the Bail still closed) and slowly pull out the knot or it will keep forming over and over again...

I use Power Pro on my spinning gear and Spider Wire on my bait casters (softer) and though more expensive to buy at first, they last much longer and much easier to pull out a bird nest (though you won't get as many) on your bait casting gear.

I have some of my bait casters that are STILL spooled with the very first lines that Spider Wire ever put on the market (whats that now 10 plus years?) and I just pull them off and re-spool them on backwards every 6 months or so. So in the long run they are more cost effective to use and both your hook up ratio and number of cast per hour (name of the game) will improve greatly by using such

Tight lines!
