Don't go to RYR!
First of all if you are an FO rated on B737NG RYR will not take you. Why? Because they can't make any money out of you. They are in the business of selling type ratings.
The company has a very good roster system and very good maintenance. However, as a pilot you are treated badly. I hear SWA is a great place to work, so if I were you I'd stay there.
If you are looking for a change of scene why don't you try one of the Middle Eastern carriers such as FlyDubai. Emirates, Qatar Airways or Etihad?
Also there are quite a few jobs going in China and packages are improving.
