The Verdict
Tortilla is a healthy presumed 18 month old but needs to be a little leaner. Right now she is 13 lbs, 11 oz. My vet would like to see her get down to around 11 lbs. He said when they first saw her (for her shelter attack in May) she was under weight at 9 lbs because she is a large frame cat. He said she is long, large head and definitely part manx which means she should be a larger cat but she is overweight and that is dangerous.
He recommended wet food for the same reason you all have, it is high protein and lower carb. He said she should lose weight slowly because even though she got chubby fast, cats tend to be slow on losing weight. He does not believe based on her exam she has anything wrong with her, just needs a better diet. I am so glad, now if she forgives me for taking her to the vet we will be set! 
Edited to add- My vet feels the "dry food helps teeth" idea is a myth. He said if you watch how cats eat they break the food in half and swallow it. They don't really chew, he said that while he does think their dental health is a concern he doesn't think feeding dry for the dental benefit helps. I do notice Tortilla seems to enjoy the crunching based on her preference for crunchy treats over soft (which I haven't been giving her much since she got so heavy) so I may keep a small bit of dry food as a nice change.
