I was wandering if anyone has used/uses a really low fov to play with, like Daler used to use back in the day? (cg_fov 69)

I've never really been able to use zoom effectively so I've alwayed used a low fov, so I'm playing around with lowering it. I'm not really going to be able to test it out properally until I get back to the UK and I would like to know what your own experiences were with it?
