Gotchya- like I said in post #13, I don't use the stuff because I don't build any road specific, light-duty/race-only bikes.
Still, the shaped Spirit has been/still is used effectively by others- and while the OP clearly isn't ready, I wouldn't disparage a builder with the design and fab skills to utilize those tubes appropriately.
