after having a very similar problem myself I asked the same question on here & the advice I went with was to swith to a mono mainline with a leader.
I have started using a 12lb mainline with a 30lb braided leader ( lenght of the rod with at least 6-7 turns on the reel) and have yet to crack off again !
As I said I faced a similar issue & wasnt sure if was duff braid, or beacuse they braid kept drying out or if i had over filled the spool and the line was wrapping around the rings. What ever the issue was its sorted now I have switched over.
