XTOL I mix it up with a little rodinal.
I think he means that the D76 pack contains different chemical powders which may separate out slightly in transport so that if you take a small sample from the D76 pack, the different constituents may be present in the wrong proportion.

What for? The operating range for either, by pH, would be very different - Xtol has a near-neutral working point around pH 8, where Rodinal is at pH 11 even at 1:50. In small amounts, the p-Aminophenole from the Rodinal will do nothing, as it needs a high pH, and once the added Rodinal gets past the Xtol buffering, you'll inactivate the Phenidone (which requires a low pH) and and end up with a p-Aminophenole/Ascorbate developer of somewhat undefined concentration and properties. If you really want something like that, mix it from scratch.

I use D76 and always have. Never tried XTOL. So?So ... I wonder how many people who have never actually tried XTOL will back D76?
Shouldn't be allowed to vote I reckon! 😛
