I use braid for pretty much everything with the exception of a squidding combo spooled with 12lb mono and a 15kg trolling outfit.
I only use mono on these two for the added stretch, with squidding I find I don't pull jigs as often and for trolling I like the shock absorber effect on strike.
Since starting to use braid a few years ago I don't think I could go back to mono for most of my fishing, I love the stuff, for bottom bashing there is no contest.
As for the breakages- if its fireline you're using, I have had problems with dodgy batches in some of the spools I've bought where the line snaps mid cast in the middle of the line for no reason. I had this problem with 20 and 30lb fireline in the bright pink colour. This line seems to go to shit a lot quicker than a lot of the others.
After it broke on a couple of casts I ripped it off both reels and replaced it with FINS and YGK.
Both of these have been great, infinitely better than fireline.
Cheers
