Hi SST4270,
Thanks for the feedback on the search function. Were you using the site search or the forum search? I’d also appreciate it if you could let me know a couple of search terms where this happened as it may help to figure out what is happening. I just searched the term “sag factor” and the site search came up with 5 pages where both words occur (the default). I also re-searched for these two words used as an exact phrase and there were 3 pages. A search for either of these words came up with 35 pages. The site search only searches the site itself (not the forum) so a search on the forum search engine will come up with these terms used in the forum. I may have to look at a site search that includes both … could this be what happened?
While the Baltimore - DC corridor is not great when it comes to independent manufacturers … there are a few places that would certainly help with getting a sense of the layering which would work best for you. This thread should help a bit.
You are wise to do some testing first IMO. While online manufacturers are a great source of value … especially when there are no local manufacturers available close by … your own testing will really help you be more accurate in the layering you select.
Good luck … and feel free to post if you have questions along the way.
