Yeah man that would be way to low time to be leaving.
If you had 5k and 4000 121 I would say you are not closing the door for the majors. However leaving with only a 1000 121 will have recruiters at majors wondering if you just couldn't handle the lifestyle even though it's a crap show. I'd say stay on a little longer and hang in there man.
135 is a hard lifestyle too. Pastures aren't always greener on the other side...
