I've had a pair of Trango Extremes for a few years now and they're about beat.  I was prettty set on replacing them with the new version (the Extreme S), but just read the fine print and discovered that they're not entirely synthetic, but use leather as well. 
  
I'm kicking around the idea of getting a pair of the Trango Ice, since they are entirely synthetic uppers, but I don't know if I dig on the power strap and built-in gaitor garb. 
  
Add to this, the fact that the lasts appear different from my old boots and I'm quite confused.  I'll hopefully be able to try out both models this fall at a demo or two, but until then, some opinions would be great.  Bear in mind that it will mainly be an ice/mixed boot, but also used for alpine climbing (primarily in the rockies). 
  
Thanks
