Hello -  
  
I'm climbing Mt. Rainer on June 27th and I'm looking for suggestions on boots.  The guide company recommends double-plastic boots, but I would really prefer not to wear these due to weight/comfort.  
  
I was hoping that La Sportiva TRANGO EXTREME EVO LIGHT GTX might work, or the new TRANGO PRIME.   
  
Any help would be greatly appreciated.  
  
Thank you, 
  
Eric
