ORBX/FTX Scenery Library Order

Hi guys. After a bit of advice please.

I've just recently got FTX Vector and the new OpenLC EU but am getting confused as to what order the scenery library should be. The reason is I've uninstalled UTX EU and am finding the OpenLC doesn't seem to add much with lots of details missing when compared to UTX?

PS have FTX Global installed.

My library roughly is:

1. UK2000 Airports and payware airports

2. FTX regions Eng/Wall/Scot

3. Addon scenery

4. FTC OpenLC Eu

5. FTX Vector

6. Default FSX mesh.

Thanks
