All the fish we managed to land were F1's. I've since ordered some different elastic due to earlier comments, the lake was a snake lake type so a slope away from me, I thought when the bottom sloped away you flicked it out in front of you and waited for it to settle? Complicated old game this fishing
Definitely the elastic then, I reckon you had a fish on and they only managed to get 2 meters of elastic out and the hooked was pulling, F1 are very delicate feeders and most are only lightly hooked in the lips, hence why you need light elastic.
The only time you need to lay line out like that is if you were fishing for roach or a very sharp deep slope to fish the side of the slope , but then you pull your pole towards you at the same time, no need to do that at all on a snake, if carp or f1 fishing it is better to lower it straight down, chances were you were getting a lot of missed bites which were liners due to the way you were feeding while laying the rig in.
