Just got it friday,
set it up with Randal Luge trucks and lime and lemon bigzigs
this thing is the funnest time of my life. Weighs about 30 pounds all together.
Got it up to about 80 last night, man does it ride sweet. I love it.
This is my first luge ever, so I don't have anything to compare it to really.
But I had no problems getting it around corners or anything, and it was actually really smooth.
There was a bit of drifting when I was up to about 50 km/h around a 90 degree left hander and I sat up a bit to slow down and I felt it drift a bit. But besides that there wasnt a whole lot.
This is a article about his current luge and it seems that it is just like yours, but with fairings: http://street-luge.com/phpbb2/viewtopic.php?t=117
You can contact him there (at street-luge.com). His username is SMRTIC. Possibly he has more information for you.
