Hi! I have taken a picture, showing my 10" coil, equipped with one of the new spun toroids. Performance is great, there are no problems with the seam, even a toroid, where the shells were put together, without any glue, or finishing grinding, the streamers mooved frely over the joint. http://home5.inet.tele.dk/f-hammer/spuntoroid.jpg Cheers, Finn Hammer
