I don't think any team is going to have their build held up waiting for FIRST Choice, to be honest. Or, rather, no team should have their build held up waiting for FIRST Choice. FIRST Choice is a somewhat random selection of items that happen to have been donated this year, with no guarantee that you will get the item you want. It is not a standardized set of parts that a team can or should design around.

If your team has such limited resources that you need a part from FIRST Choice to complete your build, you should probably rethink what you're building, and rethink your design process - there's plenty a team can do with a kitbot and some improvised materials (I recall hearing of a fairly successful drive-base-and-lawnchair robot last year...).

Edit: It has been brought to my attention that the robot in question was not a kitbot drive - regardless, the point remains (basically) intact. Corrected post to reflect this.
