As I mentioned there in the end I plan on ordering one, most of my go-to builds are Titanium so I'm confident I can get it to work. Voltage is the key to avoid PWM, some people it doesn't bother .. PWM annoys me but if I exactly dial-in the wattage or Joules I can minimize its effects. Since the Mod, I assume, is serial it should not pulse. It's cheap in a good way. So we'll see, I'm waiting for batch (debugged) two or later this month. ;-)[/QUOTE] I don't have an engineering background as I'm still an undergraduate student studying for eventual MBA-JD joint degree w/ history background, but I'd say I'm quick enough to understand an explanation of how these chips work. I haven't been able to find, less some schematics, press releases, & spec sheets, any solid 3rd party information as to what limits chips to certain wattages, and whether firmware updates to say the DNA200 chip would hypothetically allow for it to function at a higher wattage? Would anyone be able to explain, and I don't need an entirely layman description, whether the batteries or the chip are what hold the wattage back from being say 250 or 300W? Is it the soldering slash material quality of the chip limiting its wattage rating, as I assume all electricity passes through slash over the chip directly? I would assume that the cylindrical Li-Ion is superior to the pouch Li-Po type for power but the Li-Po is better for those looking for a lighter mod? I'm torn between three mods one of which I will buy within the coming week: Wismec Reuleaux RX200; Wismec Reuleaux DNA200; Vapor Shark DNA200. I've had terrible customer relations with the guys at Vapor Flask, which I realize are a separate entity from Vapor Shark and so is why I am willing to give Shark a try coupled with the physical mod itself having a nice rubberised finish. I suppose my question would be there whether anyone who owns an RX200 and has expertise on any level can checkout the board's manufacturing quality by eye alone, and how that would compare to the DNA200? Granted an equal manufacturing quality, I suppose it would go to preference, but if indeed the DNA200 chip is superior in manufacturing: which would people recommend based solely upon reliability & battery life, the Reuleaux or the Vapor Shark? I realize that I've packed quite a bit into a few extended questions, and so I might just create a separate thread for this but it seemed a relevant place to post it to start.
