collision-resolution

I realize this might be open ended ended but curious if I just did some over kill...

I had this

http://create.msdn.com/en-US/education/catalog/tutorial/collision_2d_perpixel

and i reworked it to work with my animation code in XNA and what not. It works well, but now I want to use this to decide if there was a collision and to have the items (characters) bounce off eachother elastically. Was the per pixel too much and I could of just used a bounding box ? (in fact would that of been preferred for what needs to be calculated in the response for an elastic collision?)

Looking for guidance really.

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
