Agree with what you are saying. PErsonally skuim i would not use that rig you posted. Far to complecated for me. I have simplified all my rigs down the bare minimium. I use to methods of floating baits. One i float from the bottom the other under a float/bobber. With the bobber fishing i use a standard polistirine float, usually with a small tilapia as bait. Sometimes it may still be wriggling. I than take about 2m to 1m leader, this i attch to a swivel. My float runs up the leader and uses the swivel to stop it. This i find makes my bait presentation more natural as it is not being pulled around by the set float. Increased my strike rate. I do use a plattie on this rig, works really well. Once he has realised he cant swim down the plattie uses the float when it trys to breath. Often gripping it and rolling it around. Also creats some commossion and attracts mr barbel. I vary my leader based on water temp at times, and if i have a decent fish finder will set the bait in the thermocline. Works very well. The other way i float bait is an american style, or what i call the american style, the british use it to. I fish it on a sliding rig, standerd issue. Than my leader is around 1m long. On this is attached a floatation device, cant remember what the guys call it. This can be fixed on the line or allowed to run free. Its basically a small cylinder. This floats the bait. Iuse it mainly on fish fillets and where the bottom is muddy. I like these rigs in summer, as the temo heats up it changes the oxygen levels in the water, so if you can find the band where the fish are hanging and out a bait at that depth its game on. Ill try post some pictures of the rigs. Im still working on it, but so far im really enjoying this type of fishing.
