The one thing I don't like about this (and the hipshot) is that it sits on the body - I've seen folks remove the hipshot and there's an indentation in the wood. No thanks for my vintage bass (I actually like the 3 point, sure not perfect, but works well), but for a new one it's OK I guess (if it's stock). Maybe it was cranked down to hard, I dunno if it would be stable if the posts were loosened as I've not used one myself. I also suppose one could cut out a protective base plate out of 1MM aluminuim or something, to prevent body damage.
As for 2 point replacement, I love my Schaller 460. No longer in production though. Bar bridge is good, but as I play higher up the neck a lot (wannabe rhythmn guitar), intonatability is a must for me.
I have wondered recently, what Wilkinson (Gotoh) would come up with if they decided to enter this market. I was recently very impressed with one of their geetar bridges on a Ric a customer had in for a setup and a pup fix (one coil dead - converted it to a single coil; now has a Fender sound option and balance between pups is surprisingly good). So (easily - philips vs allen and not under the strings etc) adjustable and solid. The whole axe was very nice actually, just didn't dig the look so much.
