Yes it is! Regarding the use of offset crowns(typically offered with 7degree offset) and straight blades, the blade length will determine the the trail, the longer the blades the longer the trail and therefore the more "stable" handling(given other frame variables are equal), correct, or do I have this reversed? Sort of hard for me to visualize this without drawing it. I realize as the blades lengthen the shallower the ht angle becomes(again, all else =), so blade length must be built exactly as designed to maintain desired characteristics.

I have heard trail described as under or oversteer(commonly used to describe car handling characteristics); with oversteer the large trail number requires more effort to turn while understeer requires less effort("you change lanes when you turn your head to spit"). I think I have this correct!

The often discussed "low trail touring bikes" need the "quicker" handling to better control the loaded bike, is that right?

Thanks for posting the graphic FTW, explains trail very simply and well.
