(not sure if OP is still making up their mind but got a notification there had been new activity on this thread) after all the research I've done and forums I've read through it certainly does seem stability trumps pretty much whatever salt you choose...with that being said, I'd imagine you play it pretty safe using a salt like Red Sea which is from evaporated sea water if I remember right...I don't think I've ever really heard any complaints about it tbh
I keep it simple, but the parameters are perfect consistently..
