You have to ask, why a 737? I did it about 3 years ago, beware you will be asked why do you have a 737 type...there is really only one reason, and as far as I can tell they are not doing too much recently.

Being typed in the 320, I can say by far the 737 is an easy deal, you will get the pre study material and will have no problem. The bus is different, hard to understand at first, but easy to fly. Just different, depends what your backround is going into training.

Like others said, good folks.
