Many thanks Paul very helpful will watch the rest of that video.. I will at some stage invest in a few casting lessons just I have to go to Galway which is about 4 hours away.. Thanks again..Most lines used to have little bumps in the line, they looked like a line fault but they were there to let you know the optimum line needed to cast and you could feel them them between the fingers when pulling the line back.
If your line doesn't have them and not many do lately, you can mark the line with a marker pen so you notice it in your peripheral vision when you find the amount of line that you need to cast.
Eventually you do it by the feel of the cast.
You can get some line by roll casting or by waving the rod in the air (false casting) I'm not a fan of waving the line in the water to get more out as it scares the fish, in my opinion.
heres a video on starting to cast
