I must disagree with anyone using or advocating use of line with
a breaking test over 30 lbs. Beetle, your 30 lbs power pro was
more than enough and yes you probably did not check the
abrasion caused by a previous catch. If it was a particularly long
fight around rocks then the time taken to pull off 10 yards of line
and run it slowly through your fingers as you reel in is worth every
minute. For years I used 15 lb Ande mono with no problems on
fish up to 50 lbs. Use of 50 or 80lb test line is for commercial
guys--meat haulers. Might as well include an electric reel~!!!
Keep at it my friend, beach fishing is the only way.
