Cakey,when i go fishing i plan the way i want to play the fish before i cast in and i am more than confident with my tackle and my ability to land fish upon the 8lb line,if i wasnt i would not use it,if howeveryou are only confident in not being broken on 20-30lb then that is your choice to make,do not come down the angling press and B.S.route that i should use 12-15lb mono which to me is carp tackle unless i say again on rocky,snaggy venues or extremely large fish are expected.
To answer Lauries point,i would like to know where he fishes because if the venues he fishes are suitable has he ever fished with 8lb line for barbel because and please do not take this as an insult for i dont know you,if you havnt fished for barbel long it has become standard measure to use 12lb line for them but it used to be the norm to use 6lb,in fact when i started fishingfor barbel in the seventies i cant recall anyone writing on the use of 8lb there were never masses of fish lost,unless lack of experience played a part,which happens in most forms of our sport.Now 8lb line is commonly advised for chub,seems incredible to me for i have caught many over 5lb on 2lb line without problem,that said my normal big bait chub gear would be 5-6lb line,the choice is your own,thankfully i am not made to follow suit and finally you seem to have missed the point,what happens when YOU snag with 20-30lb braid and barbel takes the bait because i fear that fishes future is far more certain than mine or can you pull trees out with it,maybe thats the sport in it,i didnt think of that/forum/smilies/wink_smiley.gif.
