Cougar I havent used the vapors , but if you are looking for a carbon with more weight , carbon express terminator hunters are an excellent shaft , I' m shooting a 28" 6075 with feathers and 100 grain tips that weigh in at about 480 grains . They are very accurate and very durable , my son shot one in the rock pile with his genisis and it just scratched the camo a littel , but thats another storie . They penitrate like you would not believe
