I used to shoot muzzy 3blades. I switched to slick trick and I'm happier. This is just my experience. Slick trick flies much more consistent. I still shoot the muzzy for deer and will be using the mx3 this year. Slick trick is strictly for elk. Magnum or standard? Well, I have both in the quiver. If the area around my stand is very open, I use the magnum. If not, I use the standard. They fly the same so just preference.
