I know this is non-related ExTech question, and I apoligize for that, don't wish to cause controversy or give anyone a heart attack.
That said, do you guys know where I can find what pipe does what?? I mean I know a 63 is low end and a 86 is top, but if I'm not mistaken those are EFRA numbers, what happens to the rest? Do they have an EFRA equivalent number or what??
