Hi the 1968 spine chart I have shows that a Micro-flite size 7 with a target point of 60 gr. at 28" is 48 to 52 pounds. Same arrow with a 125 gr. hunting or field point is 43 to 47 pounds at 28".I get good arrow flight with size 7 micro-flite at 29"  with bear Razor heads around 48 pounds off the arrow shelf.
