Well in the good old days (i sound old ) 99% of tip fishing was done for silvers/bream and as cob,kieran has said it was all about sensativity
ue,d set your rod up as normal and were your tip was u,ed put a little target board with lines on and then if u lined ur tip on with one of the lines you could see then bites if it move from 1 line to another !!!!! the bites really would be that shy
But only for the silvers if you had a better fish ya tip just use to start bending and keep goin
