From testing pike over the last couple of days I have found out it is best to catch them when there's a ripple on the water, more than 0.5m/s - the higher the number the better.
I have only tested the poppers shown below,. I'm sure there are other lures out there that work better. I have marked where I catch pike below. For the tench, I have caught them off the bridge casting in to the pond. For the eel in one of the screenshots above, it was caught in the black area of the screenshot below. All screenshots below show setups and positions of fish.
Flouro leader used is 15kg on the carp rods.
