Hey all... Current X75d owner with a Raven P+L on the way. Is the upgrade to speed and acceleration really noticeable? To me, the 75 seems pretty quick when I accelerate, so I'm curious what it feels like for the P model... Also, what's the difference between Insane/Ludicrous/Ludicrous+? Do people keep it in Ludicrous mode the entire time, or does that drain the battery faster? Is Ludicrous + only for special circumstances? Unfortunately, I don't have time to go test drive one to answer these questions, so I wanted to get some real-world opinions from other owners. Thanks!
