As you make your decision, you might want to consider applying the WARP decision framework from Decisive by Chip & Dan Heath[0]:

1. Widen your options

2. Reality-test your assumptions

3. Attain distance before deciding

4. Prepare to be wrong

The heath brothers offer a useful workbook[1] that goes into details for each of these steps. It might be worthwhile to go through it as you decide.
