Code Size Limitations

Question

Hey Flexsters,
So I am building a form/bid estimator, and I have added <mx:Model> lists in XML format to populate ComboBox drop downs. So far I have 3 of them, combining for around 1500 lines of information.  Is there a best practice amount of info to use in the <mx:Model> area that I should keep in mind?  I have a few more ComboBox(es) to add to the app, and wonder if I am going to make it slow or disfunctional if I get too much information referenced that way.  Is there a better way than what I am doing to populate a pull-down menu?  Sample code below:
In the top of the Application source area I have this:
    <mx:Model id="signals">
      <signaltypes>
        <signal label="VUC (included)" data="VUC"/>
        <signal label="IP Endcoder-Onsite" data="OSIP"/>
        <signal label="Fiber" data="FIB"/>
        <signal label="ISDN" data="ISDN"/>
        <signal label="Satellite" data="SAT"/>
      </signaltypes>
    </mx:Model>
Then placed in the Panel I have:
<mx:ComboBox dataProvider="{signals.signal}" id="signalTypeCombo" editable="false" enabled="true" change="this.selectedItem=ComboBox(event.target).selectedItem" x="10" y="37">
This is the smallest of the sources - I have one that lists the 1000 largest global cities...so I am not sure if I am going in the right direction, or if this is exactly how I should be populating the menus.
Once a selection is made, I have another panel to display the selected options which I am hoping to have printable in a summary format, but I am still trying to figure that part out...I just want to make sure I am building the data selections properly.
Thanks as always for your advice!

no takers so far....
So ammending my question a bit, is this a better way to create the functionality, what might be the advantages to using <mx:Model> vs. <mx:DataProvider> with <mx:Object> structure?
Same effect but different, not sure which is better..thoughts?
<mx:ComboBox id="signalTypesCombo">
<mx:dataProvider>
<mx:Object label="VUC (included" data="VUC"/>
<mx:Object label="IP Encoder" data="OSIP"/>
<mx:Object label="Fiber" data="FIB"/>
<mx:Object label="ISDN" data="ISDN"/>
<mx:Object label="Satellite" data="SAT"/>
</mx:dataProvider>
</mx:ComboBox>
Thanks,
Rich
