My Single Point was around 7kg. Incredible if you consider that the wings were hollow. I gigged it once and my left shoulder was going in pieces... I finished the gig sitting.
The dimensions were just ridiculous for a 4 strings bass, it didn't fit a normal gig bag because of the huge headstock (easy to break and to slam into others' faces, that's why I'm bashing it) and the 10cm or more after the bridge.
The electronics weren't as quiet as you'd expect from such an expensive package. At least on the two I owned. And the balance on the Small body 30" was really bad. Anyway if you like them, more power to you! But I preferred Wals at the time, even if the slightly fenderesque construction wasn't absolutely as nice as the one on the Alembics.
