As I was playing around in Solidworks with the new VexPro/WCP lineup, I discovered that the switch from the standard .125" wall tube used in a WCD to a .1" wall tube grants enough clearance to allow for the use of a Vexpro #25 18 Tooth Sprocket. This really helps to save space in the drivetrain!
It's safe to say that I'm a fan of these new products. Can't wait to see this in use during the 2014 season!

The 16T sprockets are plenty big for 4" wheels and give you a tad more clearance.

Nice looking model.
We have been putting 16T #25 chain inside 2 x 1.5 tube for a couple of years. If you want to do a drop center 16T is as small as you can really go. Your chain will start to stretch and loosen up, rub a bit against the wall of the tube. Assembly of 18T will be almost impossible and if you are just running a 1:1 ratio between wheels why go with an 18T?
I really believe Versa is going to really change things for teams with limited fabrication abilities.

Two strands of #25 fit side-by-side inside a standard "1x2"x.125" wall tube.
We use 17 tooth double sprockets inside of our SimpleTube Chassis.
You cannot have any drop in this setup because of clearance around the chain.
Otherwise the system is great and is a nice volume save. FRC118 used this same setup for 2013 with zero failures and maintenance issues.
