BM Chest discussion - bronze, silver, gold

I mainly stick to the silver chests, with the occasional bronze free spin, and have never saved up for a gold nor won a super chest. I've found that if you save up for 5-6 spins in any chest you seem to get a little better payout than if you open one chest as soon as you have enough keys. For example: the free spin in bronze after watching an ad rarely results in anything more than 10K Ag, but follow it with a few more and I've gotten lucky with Gepards, Gareths, Boas, and the occasional Griffin. Saving up for 5-6 spins in silver has landed me all the gunslingers (Jesse, Doc, Butch), my first and only Fury, and a few Orkans. I've also found, as have others, that the payouts seem to be a little better right after the Black Market resets at the end of the month. I'm not patient enough to save up for gold, or work toward the super chest, and would probably throw my tablet through a window if either resulted in 5K Storm components anyway.
