Sounds like the best idea. I never got around to that.

I went to 70 because I found the exaggerated side-to-side and large turn radius 
of a low angle a big issue while learning. Now that I have a lot more miles on 
it, I still think I'll keep it there. When I descend I push on both pedals a 
bit, "stretching out" the frame, and that is adding a lot more to the centering 
force than a few extra degrees, I think. Of course, I've never gone over 40Kmh 
either...

Overall, the python turned out much better than my trike or tandem did, and I 
like just cruising around on it. I also don't need a lock, since I doubt anyone 
would get far!
If I build another bike, it will be a monocoque enclosed racer, a la Diablo II.

Have fun!
