I've generally used FP4 but recently have been trying a few different films including Delta 100 & AgfaPan APX 100. I need to buy a 30m roll of something for bulk loading but haven't decided yet which one to get. I used to use Ilfosol S but recently changed to Ilford Plus (Ilfotec LC29) mainly due to the opened shelf life being much greater. One shot developers suit my usage habits.(posted 9048 days ago)I've been shooting a few piccy's of my son under the same conditions (with flash) and I like the Agfa (quite punchy) but 10x8 is as large as I find the grain acceptable. I think the Delta was a little 'smoother' (graduation of tones) than FP4 but that could just be my development times (obviously different for each film).
In summary, i don't think you'll be disappointed at all.
Cheers!
