I like the stingers but be careful in bows with very fast speeds you may need to use the largest vane or fletch posible to achieve good grouping. i shot several test groups with my bows and my bowtech which shoots over 300 fps couoldnt group well with 4 inch marco vanes but my jennings which shoots 267 grouped them just fine . same arrows same draw lenth etc. so i changed up and went to a 5 inch and got excelent groups from both bows. i then tried the blazers they had the worst group of all. next i used 4 inch nap quickspins by far i got the best groups from either bow. so if you try them you may need to do a little arrow tuning and vane or fletch testing yourself. i shot one hog with them yesterday and i was very pleased . i got a complete pass through and the hog went litteraly 15 feet and stopped staggered and fell over kicking. he bled out in only a matter of seconds as i watched. it looked like you turned on a hose.
