I guess I'm slightly concerned about experienced players ;) In their Solos, if they managed to get bonuses for their Trait, Edge, and Style for a total of +3, then they're getting +1 Hold on a die roll of 4 or higher. And in the Head Out, they would get that +1 Hold on a 7 or higher.
It sounds too easy to get a lot of Hold for a bigger group, but since I haven't played with a group that big yet, I don't know how it actually feels at the table.
And yeah, I don't like that double-6's/1's idea either. :)
