I'm not following here.
Let me make sure we're on the same page...
Model 68142 ("Old" version of the 12k HF winch) specs for the line:
Ø0.375″ X 100′ (Ø9.5mm X 30.5m), Nominal strength=14,400 lb, 7X19 Galvanized Steel, Aircraft Wire Rope
Model 61256 ("New" version of the 12k HF winch with the cable tensioner on top):
Ø0.375″ X 65′ (Ø9.5mm X 19.8m), Nominal strength=14,400 lb, 7X19 Galvanized Steel, Aircraft Wire Rope
So what I'm saying is that the wire is the same gauge, but you've got 35' less to work with.
Oddly, the specs are the same for the weight... and I know that 35' of 3/8 cable isn't 0 lbs!
But yes, I don't really care for me so much, just for anyone looking at the 'old' vs 'new' model.
