The Eagle rods are available as well. I was really hoping to go with K1 rods as they are the lightest (820 grams) but the Molnar at 849 grams would do as well. I have used both in the past and never had an issue and I hear nothing but positive things about them on here. I just spent a bunch of money having custom pistons made, and had them fully milled to save as much weight as possible. I know the Eagle rod weighs 880 grams and I would hate to go with the heaviest H beam rod out there after doing whatever I could to save weight on the pistons. I saw some threads on here about the 440 Source rods weighing 735-745 grams. If this is true it is by far the lightest H beam rod out there, or at least that I have come across.
