Sounds like a winner Ed, wish I could be there.
It's interesting what varieties of citrus he likes and what he doesn't. Take the Rio Red grapefruit variety. If you've never had a tree ripened Rio you don't know what you're missing. Unlike his take, it is one of the sweetest, reddest (even showing thru the skin) most juicy and rich grapefruit one can grow and super productive. TX A&I didn't release this one on a whim nor it is the most popular grapefruit for no reason at all. At least from Corpus down south through the Valley it is. It requires plenty of heat but is also quite cold hardy.
Another he doesn't list is Moro blood orange which I find delectable. Super dark, juicy, and sweetly rich. He calls Meyer lemon "sour". It is anything but. For starts it's a cross between a lemon and possibly an orange or a mandarin which gives it a sweet/tart profile with a nice lemon flavor - a chef's delight.
Bottom line? Aside from one's gardening skills, one's location and soil structure AND choice of rootstock is what drives fruit quality. IOW, "your mileage will vary".
