In reply to An Triubhas:
Even the easier scrambles can include full gear placement or indeed actual rock climbs soloed. For me much of the point of scrambling is I normally do it without a rope, however if I was pushed into a scramble I may need a rope for on the day it still generally wouldn't get used and would stay in the bag.
I tend to see a rope as a back up for scrambling rather than pitching being part of the experience. That's why I generally would go for something short and lightweight and would compromise some of the security of having a thicker rope to do this. Obviously if that's appropriate for you is highly dependent on your aspirations, confidence and ability.
