ikanbilis - welcome to MFN !
My haruan days were many years ago - even though I still get to put in a day here and there.
The equipment that your friends are using are not unusual because of the snaggy conditions - and many of my friends also used similar.
Two of us in the group were however exceptions - we used lines between 20 - 30 lbs, 7 foot rods ( 20 lb rating ), and reels in the size of one of today’s 2000 - 3000. This meant that we had an easier time casting - and dare I say, probably even more enjoyable (?)
When an haruan takes - and this is the time you enjoy watching the bubbles come to the surface - regardless of whatever equipment you use, you should give it some free line so that it has time to really swallow your bait. 5 seconds ? 10 seconds ? There is no fixed time - and we all learn to use the time that best works for ourself.
In that time, between " take " and " strike " - the haruan is most probably going to pull your bait / lure, into it’s favorite snag.
After waiting ( 5 - 10 seconds ), you then give out a shout, and strike. Reel screetches out a protest, you take a step backwards to increase leverage - but what has happened ? The damn thing is stuck !
Now this is where the 60 lb line will allow you to pull harder than the 20 lb. Obviously my 20 lb would be the first to break. Then I wait to see what would happen to my friends 60 lb. He is in the meantime, pulling so hard that he would most probably be able to pull a cow up a tree.
Yes, there is a better chance for him to part with the snag - and if the snag is lightly anchored waterweeds - there is a chance that the haruan would still be there. But, more often than not - the fish was not there - gone ! Too much pressure or what, I don’t know - but after all the work - nyet - no fish as well.
So, in my humble opinion, his 60 lb did not offer too much of an advantage over my 20 lb. in many instances.( especially in areas where I could gently wade to the snag and use a net to land the fish )
Have a try both ways - and that is what fishing is all about - trying, experimenting, having fun - and seeing which works for you. Remember that the lighter equipment will be more adaptable to a multitude of land based fishing sorties, while the heavier equipment will be an overkill for less snaggy conditions.
Enjoy !!! [:D]
