Definitely caught on baits that have been whittled down by the creys , the last capture on the recent churn visit did me a bream at 3am ... the bait had been creyed but was happy & stuck another Stick on & out it went, back on the spot .... did me a nice carp come morning.
Nige has witnessed big carp spooking off creys so I'm sure it happens obviously this could be lake dependent,
They were rearing up at the carp on churn & spooking the carp .... they are like lobsters in there though!
