I was wondering if there can be a significant difference in quality from 1 batch of the same type of blank to the next? I use Verb datalife +r, and while I used to have PIE average around 5 or 6, I now have an average around 20. Also,how important is the PIE level....where should it be..and does a difference between 5 and 20 matter very much? Thanks for all your help, and I LOVE Slysoft products and preach their virtues to all who will listen!! Keep up the great work!!!
