Why 1W resistor, G? At 70 mA it's about 160 mW, and 100 mA it's still only 330mW being dissipated? I suppose you're worried about the worse-case scenario of it being connected to a battery bank that's being equalized (15V)?

And a 1/2W at .33W can get pretty warm. Some plastic gets warped without much heat.
