I too got frustrated with the standard 510 batts. I find that the window of maximum power is very short. The power they put out seems to drop off too quickly for me. I changed up to an eGo (same thing as a riva pretty much) about 1 month in and I was much more satisfied. With a much larger battery it has a much longer time of max power output. When power starts to drop off then the vape gets weaker.
Now I have a provari and I dont get a power drop off anymore. The provari regulates the power output so it hits just as hard on the first drag as it does the last. Also, if a particular atty or juice just isnt hitting well enough I can crank up the volts until it hits just perfectly.
If you are interested in getting into mods I recomend the ProVari (provape.com) or the Darwin. They are the "cutting edge" PV's that are out there right now. If mods are not something you are interested in right now give an eGo/Riva a shot. I found it to be a much smoother experience over a reg 510 kit. An LR atty on an eGo simulates higher voltage vaping quite well. Be aware, however, LR atties put more strain on a battery. Some have reported switch failures when using an LR atty on their ego/riva. It never happened to mine, but it is a possibility. To me, its totally worth it. Good luck and vape on!
