Thank you PhilC, I did play around with objs on the weekend and found it very interesting. But I still need too experiment with more objs a bit more before I create something. 
Dynamics is such a great tool and it produces the most realistic effects, it is so cool. 
 
Your info is going to help greatly, I did not have anything fall apart because I was experimenting with one piece objs. But this info by the sounds of it will take this a bit higher. Great stuff! 

I will be looking into your tutorials also at a later time.

Thank you very much.
