My gut would say to give the BG 100 a try for now. You already have them, right? Why buy something else if they work. I did check the GT website and the BG 100 has an inside diameter of .246 so you can use all the component you have. That arrow is going to shoot a lot slower than the Ultralights, but you did say it was for hunting and I don't imagine there will be much long range shooting involved.
Now if you find a need for speed and flat trajectory there is always the 22 Series at 7.3 gpi. They are a .300 spine and can be fitted with Easton 215/2117 unibushings that should work for the Lumenocks. This setup would be crazy fast. LOL.
