Afternoon, This issue came up in our SW-PF game last night, one of the group created a druid character that uses Spirit for the Survival Skill (Nature Sense) as opposed to the normal Smarts. I couldn't see a way in the sheet to set this to be the case. I snipped Survival and Athletics below. Athletics has a limited drop down to swap between Agility and Strength which accounts for the 'Brute' edge. It may be more flexible to allow the Attribute to be manually set for a skill if needed. I cannot see a way to adjust Survival at all.
