I wouldn't call it a blind theory, you can't just use FSDT data for the market share. I bet part of the reason FSDT KLAX FS9 had only 1/5 of sales for the product was due to the fact the word was out that it didn't play well with FS9, just my opinion of course. I really have no need to make the switch..... FS9 suits me just fine, especially with all the add-ons. Why put myself through months of headaches when I don't have the time nor the desire to switch. Plus I don't want to pony out hundreds or thousand(s) to get the add-ons back up to speed. Maybe someday but not now.
The post you mention was very good. New, dedicated, FS rig came out of it. No real reason it serves a purpose here.
I guess there is no reason to continue this thread, my original question was answered.
