Well.... I'm using D23 most of the time. It's slow, but I like the way it works. Simple to mix and pretty well documented on line: Google "Kenneth Lee". He pushed it in his analog period and still has a lot of useful info, and has been the source of my chemistry (Citric Acid stop, TF3 Fixer and another home made Hypowash). I'm also beginning the trek to include some Pyrocat-HD. I have some of SB-512 mix you can find here - and I like it, too; but have recently been focused more on D23 and Pyrocat-HD. XTOL would be worth another look perhaps, but D23 is so easy to mix up 1-shot that this is my preference in terms of controlled use.
I like using D23 1:3 with 150% more time (than Stock) and agitation every 3 minutes - if I have the time and want the effect - which is pretty sweet. My default starting point is to add 10% time to a D76 developing time for D23. Shooting EI to me is set by inspection, but I stick with the standard box speed times for development. That said, I'm beginning to engage in testing EI speed and Developing Times with the whole zone approach - even an analog densitometer I picked up from the dinosaur days.
Mostly, I'm shooting at an EI that normalizes to 250/400 X Box Speed and working that through on a spread sheet to give options for temps and dilution changes as well as N+1 and N-1. Films I'm stocking are HP5, FP4, Adox CHS II and I'm using up Delta 400. That said, HP5 at 250 is my sweet spot, but then I haven't progressed sufficiently to follow Bruce Birnbaum's differentiation in film selection by contrast levels. I have some winger rolls of other stuff, but that's to lower the price of practice shooting - like Kentmere 400 and Shanghai stuff. I would like to use some Pan F in MF-120, but the price is a bit rich, and at the same ratio, I'd be shooting at almost nothing. Other than the beautiful Adox grain (and amazing backing paper and packaging!!!), most films to me seem .....to produce a good look. I don't want to get lost in the weeds trying too many things, and would rather just get the shooting and development done to create a negative that can be crafted.... and eventually printed.
One thing about analog for a hybrid guy: You have shooting, developing, scanning and printing to work out. That's a lot of stuff to manage. I'm not sure it's any better than wet darkroom work.... but for now, it's stuff I can handle as the nearest darkroom is 40 miles away ...and I don't have the space or inclination (at the moment) to work an enlarger and paper developing in the laundry room.
