If I were going back to a photopolymer, I'd use Murakami's HVP. I liked the "see thru" visibility of the pink -- made setups on lower mesh counts easier.
I've been using Saati Grafic HU dual-cure for a couple of years now. Very easy reclaim, very good detail, can be used with solvent, plastisol, and some waterbased. Lasts 90 days after mixing if kept out of a hot environment. I've not done any long-run waterbased to test how well it holds up, or with discharge.
My biggest beef with the HVP was a tendency to break down into gummy, stringy hunks in reclaim that were harder to clean out. It depended upon the ink used. I have the same trouble to some degree at the shop in Daytona I work at part-time with Tubelite's photopolymer emulsion.
