I've had several flights in 3A and 3F. I don't mind bulkhead and didn't find the "restricted space" on this plane to be much of an issue (I'm 6'2"), however I find the F seats on the 738 to be horridly uncomfortable. They're seriously under-padded and spending more than 1 hour in them leaves my butt numb. I'll take an LUS F cabin any day over these.
