I just wanted to add that I just started using 130 BZT, which is Evan Clarke's variation on 130. Omit the bromide and substitute 15ml of 1% solution of benzotriazole per liter of working solution. Also up the carbonate. Dilute 1:3 for 3 minutes. I've only used this developer with MGIV FB so far and am impressed. The tones are wonderful, as always with 130, but now cooler. Just slightly cooler than LPD, but more cooler once selenium toned. I toned in Kodak selenium at 1:9 for 6 minutes and it cooled down very nicely.
I still have yet to try 130 BZT with MGWT but that is what I'm really excited about. I want to see just how much it will cool it down.
