LT_Matt, the more OI, the more liquidity, in turn more volatile,
but the pps movement is the prime deciding factor

OI can help to determine some volatility, but the price of the options is based more on the greeks than the open interest. OI helps you to determine how many options you should buy. In genearal, you should never own more than 2% of the OI, or you could end up controlling the price of the option.
