Hi, I recently purchased a Tin Lizzie with the wooden frame....I have to say that the wood frame is much stronger and more stable than the metal ones in my humble opinion. My girlfriend has the metal and it seems to be flimsy as she puts it, and the vibration is increditable...she now wishes she had purchased the same frame as I did....I have mine set up the full 10' and I have not notice any vibration whatsoever....I guess really just test drive test drive....I love my Lizzie....she's my queen and the price was right.....
