Scenery Library CFG / FTX Central2

Downloaded FTX Central2 and the optional freeware updates and have a question as to where one item should be placed in the scenery library. When I first start FSX my scenery library looks like this
1 FTX AA_ORBXLIBS
2 KLAX_Photo_Real_3.0
3 ORBX!OPENLC_NAMERICA1
4 ORBX!OPENLC_EUROPE1
5 ORBX!OPENLC_BASE
6 LEAL2007Final
The rest of my add-on scenery continues. My question is this, should FTX AA_ORBXLIBS be in the #1 spot or should it be just above the BASE scenery file.
