so I myself do a lot of ultra telestick fishing as well as hunt the records. Now this MUST be taken with a grain of salt as its what i do personally and can not speak on what others do.
1- you will snap a lot of leaders with these rods. in one week i can go threw over 100 leaders maybe more.
2- the wear on the rod will go up very fast. every time you go into the red on the tension bar it will apply wear as these rods wasn't meant to do this type of fishing.
3- after 1 to 2 weeks of constant fishing these fishes (carps) u will have to retire the rod or the rod WILL BREAK!
this is a screen shot of how i have MY setup. the line is mono which gives the most stretch (in my opinion) and the leader is 5.5kg to bring to the closes point of the rod"s load capacity.
if you would like proof on how if the setup works you can have a look under records= ultralight= on amber waterbody.
this is my no means a silver making setup, its just for record hunting and u will spend a lot of silver and possibly end up with a BROKEN rod or 2 so please be careful in what u do with a setup like this and i wish u the best of luck.
