I wish people would read the question fully before replying. The OP stated he was after winter silvers using A SWINGTIP.
As a regular user of swingtips the best rig to use is a paternoster with a link of at least 6 inches and a hooklink which is longer.
Upon casting make sure you get the rod into the rests before your feeder hits the deck and very carefully watch your tip as it settles, it should settle smoothly and if there is the slightest stop on thw way down strike as you will have had a bite. If the tip settles smoothly then you can tighten up whilst your rod is still in the rests, then allowing the tip to slowly drop again watching for any stutter on the way down, repeat as necessary until correctly set. Time your casts at all times and accurately recast. Sometimes having a hooklink of up to two feet is necessary but should not need to be much longer as its the last two feet of water that you will be fishing. Use maggot feeders with enlarged holes so maggots are swept out while it's dropping through the water. Remember that when casting the feeder must drop directly to the deck as possible, so sweep the rod back during the cast to allow this to happen as you put the rod on the rest.
Hope this helps in your swingtipping.
So a 6 inch link with a feeder on on one end an a micro swivel on the other running freely on the main line up against a quick change bead to take the hooklink, so a fully safe rig would not be allowed ?
Just out of curiosity Steve how long would you make your hooklink if fishing the method you described? Presumably it depends on the depth of the swim?Only trouble with the heli rig it only fishes the last 4 inches of water where using the rig l described above fishes 6 times that in a totally different way.
