I've never had good luck with mono or fluoro on baitcasters, because if the reel isn't set perfectly, you'll get a bird's nest that goes all the way to the spool. You can remedy that by putting a piece of tape on the reel, say 30 or 40' in and then you will only backlash to that point. Bill Dance taught me that one.
I usually use braid with about a 7-10' flouro leader, which seems to work pretty well. I use 20lb Berkely Vanish and rarely get bite offs from pickerel, and seem to catch a fair amount of bass. I even use it for ice fishing leaders for pike and stuff...it's pretty tough.
not to say your wrong, but to say line isnt the issue. i started out with braid on my first baitcaster and nested everyother cast, and braid would cut up my fingers trying to get it out. you just have to get the feel for the reel and how it works. i use fluro more that any line i have. you have to remember if you only have one baitcaster and your using different baits/ lures say from a spinnerbait to a 1/4 oz jig you HAVE to adjust the brakes before you cast or you will nest up. thats where people can start to think its the line.
you can use any type/test of line on baitcasters you just have to tune them. and its sounds way more complicated than it really is.
if your using braid for alot of lures you can lose the presentation.
