FSX and Add-Ons Reload

Hi Guys,

Have had to reformat my HD after fine-tuning my FSX system since 2010 and I"m wondering which add-ons I should reload and which I should forget.  Just before the computer t.a.p. (took a poop) I was having some elevation problems between some ORBX scenery (alaska) and some of my previous add ons.  What I had installed was the following:

• FS Genesis Mesh
  
• Ultimate Terrain X (UTX)
  
• Ultimate Alaska
  
• Ground Environment X (GEX)
  
• Real Environment Extreme Overdrive
  
• All ORBX North America scenery areas and many individual airports
  
• Vancouver
  
• Glacier Bay
  
• Tongas Fiords
  
• Plan G
  
• Etc.
  

Any others you would recommend?

Thanks a lot for your help with this
