Clay, I'm going to agree with Rob and disagree with Oscar.
I have seen only two Peach Cobbler fruits, and tasted only one, but that one was definitely in the OMG category for flavor. Visually, they were smallish and not pretty -- qualities that can work to the advantage of a mango enthusiast.
You already have a fine collection, and seem willing to experiment with "Florida" mangos.
I have no idea what is "tried and true" in your growing conditions. I suspect that data set is limited at best. Plant the Peach Cobbler and in a few years you can share your experience with other California growers.
By the time Fruit Punch is available (if ever), you may have decided that one of your other cultivars is not pulling its weight under your growing conditions.
