First off, you should be asking this in the Q&A thread. Second, best spend those gems on xboosts and guaranteed captures.
Get the permanent ones. They're much more worth your money. As for characters, just save them for strong evolutions that require SGs such as pumpkinlord's legendary and Templar. Besides evolution, just save your soul gems for characters you have a really hard time catching. Anyway, I reeeaaaaally think we shouldn't go any more off topic than we should.
