Carpedeim,
I have run straight 20lb Ande for the last 10 years with a Flouro leader and never had any problems with break offs , just a novice that thought he'd SLAM the hook home after a 200 yrd. run on a big king last year. As far as 4 releases you did good we were 1 for 2 and it was a 1 lb king 50 down over 190' on a DW Sniznit SS 40 back. Keep at it , it's going to get a lot better in a few weeks, just need to get threw the June set up period then all hell breaks lose out there.
