In reply to Oli:
Picking up on the the OP - sounds like you might want one ski setup to fit all...
Tricky. You might have to compromise in some respects, as I'm sure you can appreciate.
If you're are more serious about the downhill - and the reality of rock/heather/ice scottish conditions (plus going overseas to resorts) - you might want something more heavyweight. For example, I myself (170cm/70kg) have a typical "combat" and piste bashing setup based on an old pair of Iki Movements (178cm long/117-80-107) for which I don't care too much about the bases, and (crucially) Marker Dukes for simple, solid and secure side-country/off-piste. But they are as heavy as anything.
If you are serious about being able to walk in when, ideally, the conditions are right, then the modern lightweight setup based on dynafits makes sense. For travelling fast and enjoying good conditions I have another setup based on the shorter=lighter BD Stigmas (168cm long/114-80-104) and Fritschi Vipec's. These are a joy to skin up (although the binding can be a faff sometimes to get in and pop out of). However, coming down if you hit any Scottish "boilerplate" they will chatter rather disconcertingly, and breaking through crud takes a change in style. All part of the fun.
The guys at Alpine Guides have some great advice on various ski setups

Also, lots of good ski-touring clubs about these days - who can hire you out gear to try. This seems a nice club, and ideal for someone moving to the Inverness area:

And as a final pointer - Telemark Pyrenees are good for gear
