You are "supposed" to shoot aluminum moons.....or so they said but this year they have a deal for a lighted nock with Lumenock so that goes out the window. Now I shoot omnis with great accuracy with BE arrows and I have tested some 20" GT 2 lately just for tickles and grins and, at least with field tips, they shoot great too. I haven't got around to broadheads and GT 2 but I will. I do recommend BE arrows in these bows for now or GT 3. Blazers work fine and shoot great. My GT 2's I am testing are 20", blazers, omni nocks. I have also, just today, ordered some Jnocks. Cossack is shooting them with great results so I'm diving in myself. I will have to report back later on those. Refletching, if you buy omnis they come with an insert for them you can use in the jig, not sure how jnocks do in a jig but carbon express has a rubber nock I use and it works very well. I use right helical.
