Thanks for the input and advice. I suspect that you are correct with your diagnosis. I'm probably concentrating too hard on the "white mouse" and the d loop has started to collapse/lose tension before I begin the forward stroke.
You kindly offered me lessons at the start of my adventure into double handed casting but I didn't want to pester you while you are convalescing.
I will happily take you up on the offer when it warms up a bit as long as I'm not intruding on your (fishing) time.
I'm not familiar with the Durham water, only fished it a couple of times during fmd crisis and I'm not even sure I was in the right place ? Certainly don't remember it looking like your videos lol. It was at night though!!
I'm just trying to learn a couple of casts to enable me to fish either bank. I'll sort you out with a brew and dinner in exchange mate ?
No bother mate.We can sort a day out when the weather is Ok.
