I am shooting a daton yukon ET at 27 inches and 60 pounds and have had great luck with 125 wasp jak hammers on deer last year . I harvested two deer last year both at 20 to 25 yards and both were complete pass throughs and very short tracking jobs, one went less than 40 yards on a dead run. I will be useing them again this year dont be afraid of them they work very well ,dead deer don't lie<img src=icon_smile_dead.gif border=0 align=middle>
