static TClonesArrays

Hi rooters,
up to now I've worked with an event bases on the Event example available with root, in particular it uses a static TClonesArray as suggested in many other posts.
Now I would like, or let's say that I need the capability to have multiple copies of my event and to to that I'm thinking to remove the static attribute of the TClonesArray.
The problem is that I do not understand where and how much my code would be slowed down.
The basic structure I use is the following:


    Event* ev = 0;
    TTree *t= new TTree("...");
    for(Int_t i(0); i<nMaxEv; i+) {

          Fill Event... and the TClonesArray
       ev->Clear() // calls TClonesArray::Clear(), not Delete
    // writing tree, closing file and so on }

Thanks in advance for any suggestion,
