I love "initiative ties go to the PC". That's a simple, elegant idea that makes a ton of sense to me.
And while it probably doesn't matter all that much, using Reflex for untrained Acrobatics or Fortitude for untrained Athletics is imperfect since Reflex can come from Intelligence rather than Dexterity and Fortitude can come from Constitution rather than Strength. It doesn't necessarily matter (maybe a good Con should be helpful in breaking free of a grab), but it's another level of rule change.
