I tend to play mid day and sometimes midnight to very early morning.
Prime play time is typically somewhere between 5pm and 11pm server time (+/- an hour). So for you:
east coast server prime time would fall into the 4pm to 10pm Texas time
west coast server prime time would fall into the 7pm to 1am Texas time.
With this and your preferred play time in mind...
on an east coast server you would probably be logging off as peak time hits
on a west coast server you would probably be logging on as peak time ends
If you want to play with others, you are going to have to consider altering your play time. If you cannot do so then it does not really matter what time zone server you play on because either way you will not have many to play with.
