Hello guys. I'm pretty new to the sport but allready have some gear. I need some advice regarding Etha 2. I think is a great gun but thinking about some upgrades - carbon barrel. So here is my questions. I seen some deadlywind barrel but got no idea about a difference in them. Second I do believe I need a freak kit to it but that's another problem - do I need a whole set, front and back, will the old one fit and what thread do I need. And most of all is it really worth it comparing cost to performance. Thanks a lot in advance.
