If you shoot a drop away rest the Blazers are about tops with good stabilization. If you shoot a traditional contact rest you may want to stick with the duravanes as getting clearance with the larger vanes is an issue. I shoot the Blazers on the Trophy taker rest and have no issues. They shoot well. I have a buddy that had a NAP rest of traditional style that could never get the vanes to stop interfering and had to go back to the lower profile vanes. Just a thought.
