I liked my 27" omen so much I bought a 28". Now I have two. I shoot with a longer loop on my 27 and shoot my 28 with a short loop on the short stops. Not much difference between the two. Mabie 1/2" to 1/4". They are both quiet, accurate, forgiving, and did mention Fast. I like the draw cycle on the omen better than my x-force 6 hf also. You get use to the hump/valley at the end pretty fast, at least I did. I realy like the wall on the omen, it is MUCH better than the wall on the hf cam. I have never shot the gx so I cant compare the two. Thats my opinion, Hope it helps.
