1st opinion of many, i'm sure, but my vote is for AZ-EZ for ALUM rt hand helical. This setup has 8 degrees, works well w/ 2"Blazers or 4" Duravanes, rt hand tightens points going into targets vs lt hand loosening them. you need the ALUM version as the carbon version is for smaller diameter carbons than xbows use. have a ball!!
