anyone use burgard long travel arms?

[avc8130]

I am thinking of getting burgard long travel arms for my z400. Noone at z400central has this setup, but you guys over here seem to have everything. Im sure their quality and design are very similar. Tell me what you think. They are significantly cheaper than the mainstreams. And they sponsor our site, thats the main reason I am considering.
thanks

ive seen them after they were done being tested on 3 or 4 local quads. they showed normal signs of use but no failures. the new ball joint design seems to be the ticket.

zracer uses the same design but in a standard shock configuration. other then slamming them into every rock and tree on a gncc course...they are still doin fine:p
