I have always used this or bromorphen. I really like Neutol 1:11 on ilford FB WT - gives lovely rich blacks which appear quite rapidly in the tray, then the highlights build really slowly so there is a good opportunity to "grab" the print if you want to prematurely end the development for any reason.

I'm not overly keen on using it with MGFB neutral paper though - it has an unpleasant greenish tinge, although this is easily removed with a dip in selenium 1:15 ish.

I think Barry Thornton used to keep a bottle of "old Brown" neutol and would mix this with fresh developer to give a richer warm tone and less contrasty working solution - I have some to try this but havnt got round to it yet so cant comment on it's effect.
