We play for SCL. I am GMT-4. Sunday is going to be pretty much impossible for me as I have family in town throughout the whole day. I would prefer earlier on Saturday -- 9am to noon my time is ideal, but I can do an hour earlier or an hour or two later if needed as well.
Weekdays work for me after my work, but that will be late for you as I am not free until 4:45-5pm my time and only later in the week.
