I ordered a Mars Blade a couple months ago and mounted them on an old pair of MLX skates. I absolutely love it. My favorite aspect of it is how customizable it is. I constantly tinker with my equipment, and this is the 3rd pair of converted skates that I have made. Being able to tighten and loosen the frame really lets you dig into the skate. With the MLX holder being screwed on, I was able to play around with the setting before drilling some new holes on the boot as well. Once you are out skating, you get far more feel than any inline frame that I have used before, including sprungs. I hate to sound like a homer, but if you give the Mars Blade a chance, I think you'll love it. I am skating better on inline than I ever have before, and with much greater feel and stopping power.
