Hello everyone, I have recently aquired a Silver Saber II machine with what I believe is the standard coil or head (8 inch concentric.). I'm interested in upgrading this coil with a newer one, be it larger or smaller in size. I have read that going with a web type coil will give a little better performance. Anybody have or still use a Silver Saber II and experimented with different coils willing to share their finds? Thanks in advance, Karl
