Paul I'm a little late responding to this, but for you're project you may want to give Fuji Acros and Neopan a go. IMO a very beautiful film souped in Xtol.
Kind regards

I'd go with Fuji ACROS or Ilford FP4+. IMO, the best 100 speed films ever made. The ACROS will give you smooth, creamy tones, long tonal scale, with no visible grain, if that's your fancy. FP4+ has to be one of the best traditional-grained films ever made. Hard to go wrong with either.
