Bike Mielec

Hello, I've been following this thread for a while and have finally made the decision to go through with the purchase of a mielec, but I have a slight problem- I really dislike the mash style down tube (it seems to be just to fat) .Thus, I turn to you , all knowing LFGS community. Please suggest some geometry that would solve my conundrum (the fact that I know nothing about bike geometries does not help)!

Hi,
Have you contacted them yet?
I emailed them about a week a go, haven't got any reply
