In reply to edwardsbbrown:
I have a 1 ski set up. Rossi Soul 7s (original in 180, should have gone 188) and Marker F12. Has been used for family piste holidays, off piste and day touring. Would happy use it for multi day tours despite obviously being heavier than a dedicated touring rig.
Soul 7s
Piste - Obvious limitations as they are wife but side cut allows them to actually be quite fun carvers, though getting over the top edge can be a challenge. Very icy posted or high speeds obviously emphasises their lack of stiffness but they are capabale enough
Off-piste - Total playful joy in powder though again, at high speeds they start to suffer. For up to medium speeds, playful skiing and trees they are ace. Light tip and tail, easy to initiate turn but will hook up if careless in less than ideal snow. Not sastrugi charger but not really a priority.
Touring - perfectly fine. Obviously they struggle on a steep icy skin track but good technique overcome some of this. A minimal side cut ski would obviously be better but would make it less of an all rounder. Thoroughly enjoyable in descent but funky snow makes you work harder than a slugger ski would, better than a floppy skinny touring ski though obviously.
Marker F12 - picked over the Fritschis as they ski far better (none of the slop) and skill tour well. Picked over Dynafit as chasing kids around a resort and having to get in and out of them a lot I couldn't face the Dynafiddles again.
Basically, I'm really happy with my set up. A bit jack if all trades master of mine but allows me to just take one set on holiday and I can do what I want depending on conditions.
(For info, paired with Scarpa Freedom SL boots)
