I called and talked to MF this morning to ask about the 5.0. This is what he told me. He said it was clearer,cooked quicker, was about the same firmness as the regular formula, possibly slightly more flexible and less expensive. All the additives (heat stabilizer, softener, colorant etc.) used with the regular formula will be compatible with the new formula as well. Bubbles and settling shouldn't be an issue either just like the regular formula. Also sounds like all these differences are marginal. the biggest advantage of the 5.0 over the regular formula is the cost is lower. I plan to order a gallon to test myself before making my next 5 gallon order.
