First, I'd go in the higher resistance direction for safety sake. You can always lower it. Don't forget there is going to be a very nasty surge during warm up.
I also find it hard to believe that two watts is high enough rating for that much current draw. I've seen five watt tesistors in ac dc radios have a melt down, and, they draw alot less current than a tv set does..
I lean in the direction of saying resistor should be at least 10-20 watts wire wound. Twenty five is even better.
I also find that it's best to start high, and, work my way down, rather than starting low, and, possibly blowing electrolytics.
