Not at all.

If I come across the article, Ill post it, but I believe the reason had something to do with a measuring conversion?? I really do forget the exact reason. Brett over at Landspeed did post some good info though, from his testing:

http://forum.grrrr8.net/showthread.php?t=30585

I considered picking up a set if I could find some bare at a good price.
