Hi Greg, I have the FA 50/1.4, FA 31/1.8 limited and FA*24/2.0, and I regard the 31mm as the "normal" lens for my *istD. It's a fabulous lens, and gives about the same AOV as a 50mm on a 35mm film camera.
The FA*24 has an issue with chromatic aberration that has made some people disregard it for use with *istD. I don't have enough systematic experience to comment on that myself. So with your options, I'd go with either the 35mm or the 28mm. Personally, I would lean towards the 28, but that's really just a matter of taste. I think both the 28 and the 35 are very good optically.
