You need a speed increasing developer, of which Rodinal is not. It won't be a big difference, probably less than a stop, but some developers will do better in the shadows than others. I can't suggest any commercial preparations, as I mostly mix my own stuff, but no doubt others here can chime in with some good suggestions. This doesn't apply to Rodinal or HC110, but for almost everything else, use absolutely fresh developer. I've noticed that loss of shadow detail (speed) is the first thing to go. If you use a liquid, make sure it was manufactured recently. If you use a powder, use it within a couple weeks of mixing the stock. (My favorite with FP4+ is FX2- you can also buy Bill Troop's modified version from the Formulary. It will pick up maybe 1/2 stop in speed. Do a mild push.)
