my apologies, my current bow is set at 68 lbs with 29'' draw. the arrows are victory 340 spline with 100 gr broadheads. the total weight of the arrow is approx. 390 grs. im hunting blacktail and mulies but more range time than anything. mostly looking for speed than anything.
I personally consider that to be to light an arrow for hunting. Will it work yes. I would use 50gr brass inserts and a 125gr head. A soft cam doesn't require as stiff a spine as a Hard Cam. So when looking at the charts look at draw weight, type cam, arrow length/draw length. I tend to agree in general it is better to over spine than under spine.
