Iv'e had a fair few Barbel from several different rivers over the years. My setup has remained the same every time, straight forward free running link, with this i can switch from a weight to a feeder in seconds. I hear all this talk about different rigs, and to me it just seems to complicate things. Is there any reason to go using these fancy ( and sometimes complicated rigs ), are there really any better rigs than the straight forward one that i use ?
