I would say take a look at the CF boundless its much more portable than the cfx, and i'd also take a look at the Vivant Alternate thread, many ppl are giving it rave reviews. i would say the Arizer Air, but its not for u if ur concerned about draw resistance, in fact the Vivant has a draw resistance lever u can mess with to fine tune your experience. As far as the Grasshopper goes id only get it if you need maximum stealth, it still has a lot of bugs to work out, the batteries don't last that long and i think its outrageous they upped their price considering how many faulty units ppl have received, if anything they should have lowered the price to 150. As if frequent RMAs aren't annoying enough, i can't imagine the mental and emotional drain of constantly worrying if your hopper is failing, getting hot, producing wispy vapor etc.
