I have being using the Combi-rig over the last 12 months, as my water is very weedy, I can chuck this into the weed using a 1oz flat pear lead and it sits nicely ontop of the weed as I use a snowman bait and a PVA nugget aswell.
I do usually fish onto the clear spots which this rig has done the job for me, but when there are fish in and on the weed, and you need to fish on the weed, as I said, this rig has done the job and put me fish on the bank. Plus catching a few PB's on this rig also last year gave me massive confidence in it.
