why do u want very high res atty on high voltage?u can get the same wattage from this high volt,high res setup with low res,low volt..remember,its not about ur volt,its wattage..V=IR....P=IV..use this formula to get ur preferred wattage setup..
v(voltage)
i(ampere)
r(resistance)
p(power)
v(voltage)
