Well, my GF had a good (and bad) first night with her B4.1 FT the other night.
I'm really impressed with it to be honest. I drive an RB5 SP2 (updated to WC specs) and I loved the feel of the B4.1. A speed control catching on fire shortened her night just a bit, but she is still in good spirits and is already getting her car ready for when her replacement arrives.
Big thanks to those who gave us gearing suggestions, her car was a rocket down the straight!
