One thing is the 8-iron in that set is like your CG4 7-iron(loft and length) and if you hit the CG4 irons better I would stick with them. If I were you I would take both sets to the range and try them against each other and see how they perform. Not sure what year the CG4's came out but I would think the Burners should be more forgiving. A blade type iron might be better for your swing.
