True, your crit, hitting 30 to 40 MPH, will be very dominated by aero.
Nonetheless, I wouldn't ignore aero for a 3000 mile race, although comfort and aero would both be important.
No draft rules on the RAAM and various TT and Tri races would certainly affect one's bar choice and body positioning.
Heading to the grocery store, pulling a trailer like a dragster parachute combined with a boat anchor makes all that seem a little less important.
