If you have the wing tube with the 3 braces leading into a smaller center tube - don't use it. I plan on replacing the one that came with my kit as I have seen one bend on a buddy's plane that should not have done so. TBM sells one for about 70 bucks:

I would have thought you would not have got a better tube than the one with the web ,Mine has come out at just under 400gm 990 mm long .
