Here is my math: Sin of 30 is 0.5, meaning that for a 30 degree angle the vertical component is half of the tension on the rope. Each end carries half of the weight. So for a 200 lb weight, or any weight for that matter, the rope tension on each end is the same as the weight (multiplied by 0.5 and divided by 2).
W = weight
W*0.5/2 = W/4
The thing to worry about is dynamic tension, not static, me thinks. Getting mass times acceleration involved, and all that.
