I'm toying with the idea of using BV instead of C-Bills for campaigns since I feel like the C-Bill costs get really wacky for units with XL engines and other equipment. I plan to use BV to purchase, sell, and repair units. While buying/selling units is straight forward, I'm not sure how to treat repairs. Perhaps make it so that repairs are equal to the difference compared to a full-BV unit? Any other thoughts?
