In reply to 15jacobj:
Your biggest challenge is going to be finding the right conditions.
Last winter was poor with little snow and warm temperatures limiting winter climbing to those able to get out at short notice. If you can only do weekends and are based south of the central belt then opportunities might be scarce. Fingers crossed for a decent winter this year.
Another thing that might take time getting used to is how miserable the cold dampness can be compared to Canada. I always take 2 or 3 sets of warm gloves as they eventually wet through, the weight penalty easily offset by all day comfort.
There is far more mixed climbing than pure ice in Scotland, I tend to treat the ice pitches as bonus sections rather than the norm.
Having said all that, good conditions do occur, have fun!
