For me in a colder zone(6b),Southern Brown Turkey demonstrated it can ripe properly every year.
That is why it is valuable for us in the north east.
For Texas,and other hot Summer climates,I bet English Brown T,as in post #12(Danny),I think it is the best choice because it is a larger fruit,and when ripe properly,it is a very good quality,fruit,but it needs the warmer Summer to perform properly.
