play them and find out. Any of the folks here that care will tell you to post screenshots or they cant help you based on the lack of information you have provided.

Others will tell you that the SA means crap anyways and to go with the best/fasted trainer, which is the GK that is worth more, most of the time.

handling is but one of the traits and again, others will tell you that it is the overall quality that makes a difference, not the individual traits.

Myself, I am trying to find out more about the game and am finding that the more I find out, the more I dont want to know.

Good luck with your GKs. I would go with the one that is worth most, and/or the higher quality one.
