Wow! My concerns were certainly thoroughly addressed. RCU is great. I will definitely go on using castor after reading all the input. And it's not just the opinions, it's also reading about everybody's experience with castor and everything I've read here really makes perfect sense. I also have never had problems with castor, as say all my flying friends, as well. I feel like we may have helped people that are less knowledgable about the product, like me, avoid being mislead. Thanks everyone.
