BRX-1, I went with the Hartman kit because he sold me on it when I called to find out the difference between his and Mountain Performance. I did not get the extensions for the hyfax, so it is just the rail extension, I think it looks pretty good but I am going to get the hyfax extensions next year because I managed to derail my track once already(no idea how). I took my time with the installation and I didn't really time it because I had to wait for parts, but it was fairly simple. If you have half a brain, take your time and pay attention, anyone can complete the install. I did not relocate my skid because Tom Hartman asked me my riding style and reccomended that I stay with the original mounting, he said I would be very happy and I am. I went with the Ripsaw and I love it, hooks up awesome, along with 138 studs(I think thats the #) up the middle. The ride is improved noticebly with the longer skid, smoothes out the studders.
