SRAM 8 speed cassettes

I am looking at buying a 11 - 32 8 speed cassette and a MTB rear derailleur for my road bike. SRAM has three models 820, 830 and 850. I was wondering what your opinions are on the 830 versus the 850, it looks like the 850 is a little lighter, does this come at the expense of strength or longevity? They are both pretty cheap so the price difference doesn't really matter.

Since they are both steel, it is likely lifespan/durability will be comparable.
Suspect the weights of same span cassettes will be within 20-30grams
of each other between the 830 and 850.
