I use my GGTS and Penelope for everything except work. For work I use my HC Mert 14650 and Penelope. Everything else I use my GG. I used to have a huge stable of PV's (Provari, GGTB, Precise+, etc.) and RBAs (4 phoenix clones, DID, DID clone, Cobra, Penelope, Oddy drip mode, etc) but lost almost all of it in a house fire last January. I actually found my Penelope while sneaking back in a day or 2 after (it was all taped off but I knew some of my stuff may have escaped and my Penelope did). Now I have GGTStealth #4775, Penelope and the HC Mert and a cheap dripper I bought a few months ago but am not a fan of (smok RDA). My GG is good for everything but bulky in the pocket at work so I got the Mert for work use. Nothing more, nothing less.
