I haven't rechecked ,but I think you mentioned that the cost of venting with the 80% came out to about the same as the 90%.Originally posted by jclancy
really impacted by what this group on this forum is saying (NO ONE saying an 80% is the right move),Is there a higher profit margin on 80%'s or something? What am I missing here?
(and the 90% was cheaper to vent...
was i reading too fast,or am i on the wrong thread?)

I will have to re-read now,but in the meantime you might get a greater diversity of answers.
