What combination are you using? I have been trying doubles out because the fusions just don't work well. Also the Gators don't work alone on the Hustler. I have tried Gators on the bottom and fusions on the top and Gators on the bottom and Hi Lift splits on the top. So far the fusions and Gators work best. Next, I was going to try the Fusions on the bottom and the Gators on top. I also have the teeth sharpened on the Gators. This has always worked best in the past. After that I have a set of Mamba blades which are similar to Gators but the teeth are much larger and higher.
