simple pike rig

Hi, I am looking for a simple leger pop up rig to catch pike. It is almost the end of the predator fishing season here in southwest france, I have some frozen sardines and would like to have one last crack at the 'brochet' . It has been -6 degrees for a while but is now warming up a little to + 4 degrees. I will be fishing a very quiet 30+ hectare lake with some large shallow areas and some fairly deep chanels going down to approx 7 metres. A diagram or some advice would be welcome. PS there can be a problem here with 'small cat fish and crays.

PM me and I will send you a picture of a little device I use for most of my static float fishing.....................

Thanks chav

I seem to have my pm switched off. I am just searching to see how to switch ti back on!
