Hey everyone, After reading the posts these past few days regarding 8mm electrodes I'm puzzled. Exactly what do you use them for? Small units of 6-8mm? The smallest diameter I've ever used is 10mm, and I use 12 or 13mm electrodes, figuring the increased surface area will give me more longevity and a better processing. Am I making another mistake? Thanks for your input. As always Best Wishes, Sean
