Many thanks,first to johnny,your answer is understandable as the trent is or can be a beast of a river,thanks for taking the time.
Chris,there is definately more sensitivity with braid,as to whether you need be sensitive for barbel on the roll is your choice.You have enlightened me as to the actual b.s. of your braid.There are two things that i am not so sure of however,you say you would hate to leave any tackle in a fish,but yourline strength is a double edged sword as if if you bounce the bait into a snag and areforced to pull for a break if a barbel takes the bait(assuming it is possible for it to do so),it will almost certainly be tethered on strong line,which is potentially fatal,whereas if you hooked the same fish on say 6lb even if you broke on the fish it is unlikely to die and if tethered could probably break this line.As for not using under 10lb b.s. ,that is your choice,i dont know what make of monoline that you use Chris butif you use a line like maxima your 10lb will probably be upwards of 12lb.When fishing upwards of 8lb line for barbel i believe most fish are lost due to snags(known or unknown)or the dreaded human error(the cause of my one lost barbel this season).
I must reitterate however that im not sure that it is possible to enjoy a fish of maybe 7lbs or so on 25-30b.s.(or even 15lb)given that it has virtually no chance of escape,but there you go i thank you both for your answers,tight lines to you both,Alan
