FWIW I have three baitcasters at present, all spooled with braid. One of them is an Abu Garcia Black Max, and IIRC it has 25 lb braid on it. I couldn't swear to the make, but I think it may be PowerPro, though I've used others. Whatever it is, it seems to work fine, and I have caught a good number of our Murray Cod, a freshwater native here in Oz using this combination on an Ugly Stick over several years. Nonecaught with this setup have been huge (these fish can get pretty big) but some might have pushed towards 20 lbs. These were caught with spinnerbaits and with surface lures.
I always have a non-braid leader with braid, to give a little bit of shock-absorbency (and because it is less visible), Usually fluorcarbon, but I also use some co-polymer (P-Line, mostly).
