kayfun mini

I have question about the proper juice flow opening on this guy. My V5 works perfect with 2 full turns opening. Does it work the same way on the V3 ?

Is there an ego sized tank like the kayfun mini, but with a glass tank? I am trying to find a kayfun mini styled RTA for a friend so they can enjoy the performance of a kayfun. This person won't deal with plastic tanks, and seeing juice level is also a must therefore it must be a glass tank...

Really enjoying my KFL+ w/ micro coil cotton on a Vamo. Still enjoy my Kgo Megas using good ol smoketech slim DCT with 1.5 dual carts. I kinda have skipped over the clearos; vivi novas, protanks, iclears, ect and have stuck with Cartos for my Kgo devices. Been looking to evolve my Kgos beyond...

so im getting a Kayfun tomorrow. I have a Vapor Shark DNA 20 so im thinking about getting the mini so itll look a little better on it, but i really dont mind a full size atty on it. So which do you think is better or do they both put out the same performance?
