11X KC PRO Gazelles are the bomb. I still have a few in stock (Sam and other interested parties can contact me if you'd like), and there really isn't a disc quite like it. The DX Gazelle is alright in my opnion, but different throwers have different preferences I suppose. I have yet to throw an ESP Cyclone extensively, they feel great but dont seem as stable as the PRO G to me. My advice is to upgrade to a star or champ teebird, slightly faster but if you find a flat top one, then the feel and flight is very similar. On the discraft side of things, the new Stalker is very similar in flight and feel. Very similar.
Otherwise a Z reaper might work as well. Hope that helps
