I was going to put the fuse in the Stingray X before going the hybrid mode route. Now that my fuse won't fit, unless you loosen one of the threads to the point, the mod looks weird...I am annoyed. I guess I won't use it in hybrid mode. (at least not now) Maybe I will get another tube for it, with a kick, so I can maybe have room for the fuse? I don't know if both will fit. I decided against a kick. The SMPL does not have a pin, as you know. It hits hard, and I am thrilled with it. I was going to put a fuse in it too, but there is no way in this world it will fit. Even my batteries barely fit. I have tried the Sony VTC4, and the Samsung 25 R. The only way the Efest would fit is if you force it. I am not going to force it, and rub off the protective cover. I had to sand the inside of the mod, just to get my battery to slide in easy. I forgot to mention that before. Now it is wonderful. The Stingray X is gorgeous but it doesn't hit as hard. (if I went hybrid I am sure it would) The SMPL has that ridge inside of it, and I wouldn't have bought one, if not for that. The price was good, and it works great. When I first tried it without working on the switch, I wasn't happy. But now it works like a dream. Yes, Retic, if it was just my state, it wouldn't be an issue. But there are so many states with upcoming regs, it is mind boggling. I don't see that in the news, and I think they are doing that on purpose. If not for this vaping forum, I wouldn't have known. Even when I joined here, I wasn't aware of it until recently. I didn't go to some of the threads to see it right away. When I found out, I was TICKED beyond belief. Usually Texas is more into freedom in a lot of things. But the PC micro managers are intent on ruining us. I am definitely going to let them know what is on my mind about this. Two bills already, with several more I hear. I have already written emails on this. They better wake up and smell the coffee. Vapers vote, and they better be aware of it. Anyone that votes for these idiotic bills will NEVER get a vote from me. You can bank on that.
