I recently picked up a 60# bow so I could decide for myself which way my body likes better. I will fool with it more after deer season.

I found myself shooting cut on contact heads accurately even though my arrows are zinging at 272 w/ 70 ft/lbs ke. I originally set this bow up so I could shoot large mechanicals (and still may), but I feel more confident with 4 sharp blades leading the way. (muzzy phantom 100' s)
That got me to thinking, if I' m gonna shoot cut on contact heads, why do I need so much ke?
