I love these little hills, and they're particularly good on snowy days. Great for keeping legs ticking over in winter. Lovely set of photos - you had a really good day for views. I particularly like the one of the shafts of light through the clouds.
Ben Reoch is a great viwpoint, as Jaxter says, and it's worth adding it. I did it with Breac and did Tulloch on it's own on a 'short daylight' day. The view of the snow clad Arrochar hills as they suddenly appeared at the little cairn was really stunning. Spent ages wandering around and had a bumslide down Tulloch back to the farm
