Personally I find that a bit limiting.
In terms of weight and compactness, the leveling base is indeed low profile , very sturdy and weighs about 14 oz. If compactness is your main concern, The Feisol CB-50D ballhead will fit nested within the reverse folded legs of the CT-3342/CT-3442 and CT-3372/T-3472 models. Here's a photo of the CB-50D nested within a collapsed CT-3442 leg set:
This ballhead is strong enough to handle most 4x5 cameras (field or monorail), a 5x7 field camera, and perhaps a very lightweight 8x10.
