Sometimes even the most obvious advice bears repetition. I always fall back on HP5/D76 (for some reason D76 is cheaper than ID11), which I've used since it was HP3. It's always interesting to experiment, but when you know one combination inside out, you're far less likely to be wrong-footed. It's closely analogous to knowing your camera so intimately you're unaware of having to think about it.
And, HP3. FP3, HPS----
we go back a bit, don't we!?
