Skyline RTA

Does anyone else have trouble putting together the tank after cleaning, also the <a href="http://www.vapininthecape.com/eliquid_c_7.html”>juice flow is really hard to close and open, I really like this tank but I am struggling with it at the moment, any tips welcome!!

RDTA that’s leak proof enough to take out and about?

I'm currently using a Griffin 25 plus and while i really like it, it's not built for stuffing in your pocket and taking out and about. Does such an RDTA exist? I've been looking at the Serpent SMM and Pharaoh RDTA as i fancy a single coil tank. Can anyone who owns either comment on how leak proof they are or suggest an alternative that has great flavour and is reliable enough to take on your travels. Cheers
