I'd warn against running a system like that; we used a fixed setup with a drop during the 2014 competition season, and was probably in my opinion our robot's biggest drawback.
In the offseason, we actuated the center omni wheel using pneumatics to ensure we always had contact with the ground. If you don't actuate it and just fix it in place, a few problems arise: you either mount it too high up, and because the carpet is not entirely level (in a perfect world, it would be, but sadly it's not), there are a few patches where you will get stuck. If you mount it too low, it will always touch the ground, but not only will it cause ridiculous amounts of friction (slowing your acceleration and speed in the forwards/backwards direction), it will take a toll on the batteries as well. You have to take the bump of the scoring platform into account as well.
Just because the bot is able to strafe in your shop doesn't mean it will necessarily strafe out on the competition field, as we found out.
