i got a .008 and a .010 to test with 28.5" gt ultralights at 28.5" with 80, 90, and 100 tips. should be between 310 and 330 grains.
You should be on track then with those blades, you should fall between those two. I just didn't know if you were shooting big 500+ grain aluminum line cutters on a .008 blade.........
