RRS torque arm 3 link

I know there is a lot of talk about the supposed introduction of the Lateral Dynamics and Evolution Motorsports 3 link setups in the near future, although we have heard that for awhile now. Has/is anyone used the RRS torque arm 3 link rear suspension setup? The main reason that I ask is that I am at the point that I am ready for my rear suspension and this system is ready and available, and if I hope to have the car on the road for the summer I had better get my a** in gear. If you have used this system or know of anyone who has, would you recommend this system, and would the LD or EVM systems have a performance advantage over the RRS. Thanks.
