I went through some past post and saw that some of you guys were getting XSTREAMS or had just gotten them. Well, what about them? Is there going to be a model w/ more ports? I dive the keys a lot and end up diving single rental tanks and wouldn't mind the extra ports. What about the "initial freeflow" issue? If you put the reg in your mouth before you open the valve does it still freeflow? I have Zetas that will blast on opening the valve but if I crack it slowly very little gas escapes. What about after tank is fully on, will they go crazy if you happen to drop a second in the water (a la cyclons)? How is the in water experience? What do you dislike about them? Come on, Give!
