Do you you think it would look horribly out of place to use a Suntour-VX or a Suntour-7 with it?
If that was all I had, I would not hesitate to go with the VX but my experience is too limited, regarding the 7, to comment on its vices or virtues. That said, I would then get my butt to Ebay and purchase the correct front derailleur. There are a few for sale right now.
