I chose an FLT98CF over the vixen and the 107 APM I was looking at for two reasons,
1. F6.3 was far better suited for my camera (1.78 aspp).
2. I wouldn't have to buy specialised adaptors etc at inflated prices (they really need to come up with a common standard).
From what I was able to find out the vixen is a fair scope for the price I just thought the William optics represented better value for money and was more suited to my needs. As I said if I was choosing between the vixen and the TAK I would go the TAK.
The shop I referred you to was this one.
