I'll bet both will float...

Do you have any experience how bad(/good) these kind on (very) light skis are (when used as all-rounder in off piste)?

Pants are hard to choose for someone else.
How about some light gloves?

I have these http://blackdiamondequipment.com/en/climbing-gloves/pilot-glove-BD801731_cfg.html and they are awesome.

Adidas Evil Eye works for me

I am 5'7" and I ski 174 K2, feels short for me when going downhill but good for touring. I keep wondering if I should have chosen 181.

I suggest 181 for you.

You definitely need gaiters when skiing pow.

You must be something like 160 cm

I have two pairs of adjustable poles, but actuallly I just use ordinary ones.

Lots of.

I know nothing about "CO conditions" and I haven't skied Shiros, but based on experiences with Gotamas I'd say that 173 is way too short for you.
I am 5'7 and I skied 178 Gotamas and they felt...

Would you recomment 5'7" 150 lbs guy to mount them on the line?
I am thinking mounting 1cm forward for easier turning since I am used to about 185cm long (rockered) skis. Do you see any reason for...

Fujas are for jibbing, you can't tour on them.

It would be nice to be able to buy from iTunes.

Pre-rockered Gotamas - hands down.

How do you folks would compare avalung and airbarg (those of you who think they are useful).

Should one have both?
Or is other enough, which one is more beneficial?

Edit: Currently I have...

Non rockered Gotamas are great all rounders.
I just got rid of rockered ones because I didn't found them as good all rounders as the old ones. I'd consider some tip/tail rockered, camber under foot,...

Forget stinking (literally) fleece and wear some wool. I'd recommend Ortovox... maybe this on http://www.ortovox.com/merino-320/merino-320-jacket-men-1

Maybe I'll just compromise (like it isn't always some kind of compromise) and mount them -4cm

Pollard skis lots of triks, but -2cm should still be pretty good for skiing powder?

Is factory recommended -6cm best allrounder?
