Rayburn Swingarm / Watts Link

Can anyone provide any info on the watts link setup with the springs and shocks on the birdcages instead of on the swingarms. I currently run the "old" style with the 400lb springs on the bars and 300lbs of bite. I would like to try the springs on the birdcage setup and get some base line info for springs and bite if possible. I would like to know if anyone else has tried this setup as well and how it worked. I noticed on the Rayburn site threads that Wayne Chinn was posting some info but is is over a year old. A lot of guys on that thread seemed to be running a lot less bite and softer springs than the old setup was. Any info would be greatly appreciated.

Thanks
