AT Ski size for Northeast dilemma

Had a warranty issue with my G3 AT skis...Without getting into the whole story I am getting a replacement pair, but it's going to be a different model possibly.

What I had was a 171 100mm ski

I have a few options for replacements, was hoping to get a 102 waisted ski in a 174.

Of course they don't have any more in that length so I'd have to take a 179.

Other option is to get the same ski in the 94 waisted version in either a 172 or a 177.

Both the 94 and the 102 versions have the same camber profile

I'm 5'10" 170. Ski Alpine ski lengths 175-186

Was liking the 171s I had because I downsized for my AT Setup.

Wanted the 102s, but don't know if I will like the 179s in tighter spots...Also not sure about the 94 waist and losing width from what I originally had.

What would you do for a Northeast mixed bag of conditions touring ski?

102 at 179.

A touring ski will be used to chase powder in far off reaches....at some point at least.....where fatter is better. Difference in length 5cm is negligible.  In terms of touring there won't be a discernible difference between skis.  You already know you can take an alpine ski in 185 in tight places, your touring ski at 179 won't be a problem there.

179/102 is just fine particularly if they are sporting some rocker.

Agree with the previous two responses.  

Honestly, I ski a 104 waist, traditionally cambered ski touring...about same length as what I'd ski anywhere.  Camber is a reliable thing to have when the conditions get firm.
