Sorry to all the "up" voters, but like peeps said, gotta go with what I like eh.
Decided to go with the down style after all. Wasn't crazy about the straight tube either, but had to try one. Don't know if it was the diameter of the tube, but something threw me off it.
So yea, got'r brazed up today:
Going to add a huge gusset up front, coming back a good 5-6"(or more) from the head tube. And a smaller one at the top-back for some peace of mind and looks.
I'll keep pics coming as I go.
Even if I'm not happy with the end result, its still good practice... Plus the motor/forks/crank can always go on something else
