I had a nice few throws at the beach this afternoon...picked up a good sunburn though! A few knocks on tjokka and a friend had a good pull from something big on a slide bait and landed a small bronzie on the next slide. Water looked great but we took the wrong tackle and bait.
Anyways, back to braid...for big carp...firstly, braid remains "fishable" even at high breaking strains. The higher you can fish, the better. Secondly, there is minimal stretch which means your rod is doing the work and not the line. You want the rod doing the work because that is why we have expensive graphite rods. Those are my two main reasons for fishing braid when targeting big carp. The braid I use is 30lb Fireline.
Braailegend,
There is not one difference between conventional and european or "specimen" fishing that stands out, rather it is a whole network of differences that work together to yield different results.
My biggest challenge about this topic is that every situation should be handled individually. Targeting big carp is a specialist fishing persuit and requires specialist tackle and tactics. Some rods you use are stronger and some reels are also stronger. Let me put it this way - you get carp angling and then you get big carp angling. That is why I don't like the term specimen angling because it is not descript. With minimal changes to you current setup, you can safely be landing bigger carp and even land a few 20lb carp (9 - 13kg). But targeting really big carp of 40lb and up requires a whole different tackle setup. You also don't start here...you start and learn on smaller carp and progress up. If you try and start at the top you will most likely take longer to become successful...
For general carp angling with european methods your normal conventional rod and reel is fine. Put some thicker line on, don't use a leader and use a hooklink with a lower breaking strain than your mainline. Use a lead setup that ensures that the lead can come off if the line breaks and you are ready to go.
Change your feeding strategy and your bait and where you place your bait and you are in business. Well that is the basics and from there it becomes complicated...
