I DL'd the B-1b and its a real nice looking plane, however, making a "stripped down" version is not a bad idea. Eye candy is great, but making a plane for those that just want to fly and dont care about a VC, or what the passenger cabin looks like, or a working bomb bay in a game that there is no need. A good example of this would be the family of Meljets. His planes look awesome, but for me, I could care less about seeing the toliet or the seating. When I modified the B-52 into the EB-52, I removed most of the interior stuff. This improved the framerate a great deal. The B-1b is a great addition and its not a bad fps killer for me, but a "lite" version would be cool also.
Just my $.02 (US) worth
