python problems.. Bouncing agents mirrorObject(lists?! , Branches

I trying to create multiple points/"agents" in different branches to bounce between GH geometries (and later each other) Each point need to have its own branch for later being able to define their individual features.

#1 problem:
I can't make my point bounce correctly (Angle of Incidence = Angle of Reflection) using the mirrorObject( function (line 32 - 35)
Error given in second step/Iteration: "Runtime error (TypeErrorException): Parameter must be a Guid or string representing a Guid"

#2 problem:
Branches in python! :-S I need to change the existing code so I can add multiple agents with different features defined in each list. Any ideas/suggestions how it could be done? 

:-)
